Neck pain after rucking can quickly take the enjoyment out of an activity that is supposed to improve your health, build resilience, and reduce stress. If you’ve ever finished a ruck feeling great only to wake up the next morning with a stiff, sore neck, you’re not alone. The good news is that your backpack may not be the real problem.
When I first started rucking in 2019, I wasn’t ready to invest in expensive gear. I grabbed an old backpack, added a couple of books for weight, and headed out the door. Before purchasing a purpose-built rucksack, I wanted to make sure I actually enjoyed the sport.
At the time, I already knew my neck could be a little sensitive. Years earlier, I suffered a whiplash injury after a roller coaster ride, and since then I’ve learned that my neck doesn’t like certain positions for long periods of time. Sitting with my head turned, carrying a heavy backpack, and even growing my hair longer than usual can all make my neck more irritable. Believe it or not, I’ve discovered that short hair is simply easier on my neck because I’m not constantly brushing it away from my face.
As I gradually increased my rucking distance, I noticed something interesting. My neck rarely bothered me while I was actually walking. Instead, the soreness usually showed up the following morning. Naturally, I assumed my backpack was the culprit.
Since I had discovered that I genuinely loved rucking, I eventually invested in a GORUCK GR2 rucksack as a Christmas gift. The difference was noticeable almost immediately. The pack rode higher on my shoulders, felt more stable, and distributed the weight more comfortably. My morning neck soreness improved, but it didn’t disappear completely.
Several years later, while training for my first 20-mile Mammoth March, I learned another valuable lesson.
Up until then, most of my rucks were under five miles with no more than about 12 pounds in my pack. As my training progressed, however, I needed to carry more supplies, including a hydration bladder, electrolyte bottles, protein bars, and additional nutrition. My rucksack weight gradually increased to between 14 and 18 pounds.
That’s when my shoulders and neck began complaining again.
One simple adjustment made a tremendous difference: I started using a chest strap consistently. Later, I also incorporated trekking poles for longer distances. Suddenly, the weight felt more evenly distributed, my posture improved, and my entire body finished long training sessions feeling less fatigued.
That experience reinforced something I’ve seen repeatedly during nearly three decades of working with active adults.
Although the backpack can certainly contribute to neck pain after rucking, it’s rarely the only reason.
In my clinic, I’ve found that the backpack often exposes an underlying problem rather than creating it. Limited mobility, poor endurance, muscle imbalances, previous injuries, stress, breathing mechanics, and even training errors can all contribute to neck pain. The added weight simply makes those issues easier to notice.
That’s why simply buying a lighter backpack or reducing the weight doesn’t always solve the problem.
As both a physical therapist and an avid rucker, I’ve learned that lasting improvement comes from understanding why your neck hurts—not just trying to make the symptoms disappear.
In this article, I’ll explain the most common reasons I see neck pain after rucking, how I evaluate someone experiencing these symptoms, and what practical changes may help you return to rucking with greater confidence and less discomfort.

Why Neck Pain After Rucking Isn’t Always Caused by Your Backpack
When someone tells me they have neck pain after rucking, one of the first things I ask is, “Tell me exactly when your neck starts hurting.” That single question often provides valuable clues about the underlying cause.
Backpacks are easy to blame because they seem like the obvious culprit. After all, if your neck doesn’t hurt during a regular walk but begins hurting when you add a rucksack, it makes sense to assume the extra weight is the problem.
Sometimes that’s true.
If your rucksack doesn’t fit properly, hangs too low on your back, lacks a chest strap, or carries weight unevenly, your neck and shoulders have to work much harder than they should. In those situations, improving your equipment or adjusting how you pack your gear may significantly reduce your symptoms.
However, I’ve learned over the years that equipment is often only one piece of a much larger puzzle.
A well-fitted rucksack should feel like an extension of your body. It shouldn’t constantly pull you backward, restrict your arm swing, or force you into an awkward posture. When those things happen, it’s worth addressing your gear. Yet even after making those improvements, many people still experience neck soreness.
That’s because the backpack may be exposing an existing movement problem rather than creating one.
A Clinical Pearl
In my experience, the rucksack often magnifies the weaknesses your body already has. It rarely creates them from scratch.
Think about it this way. If your body already has limited mobility, poor endurance, muscle imbalances, or previous injuries, adding even 10 pounds to your back increases the demand on those systems. The extra load simply makes it harder for your body to compensate.
One pattern I see frequently involves people who have built a good walking base before starting to ruck.
If someone can comfortably walk for 30 to 45 minutes without any symptoms but develops neck pain within the first 15 to 20 minutes after adding a 10-pound rucksack, I immediately begin thinking about the equipment. The pack may be positioned incorrectly, the straps may need adjustment, or the weight distribution may be uneven.
On the other hand, suppose a person feels great during the first several miles but begins developing neck pain later in the workout. In that case, I’m much more interested in their training habits than their backpack.
Questions immediately come to mind.
- Did they increase both distance and weight during the same week?
- Did they jump from three miles to six miles too quickly?
- Are they carrying more weight than their current strength and endurance can support?
- Are they becoming fatigued and gradually changing their posture without realizing it?
Fatigue changes movement.
As your muscles become tired, maintaining good posture requires more effort. Your shoulders may begin creeping toward your ears. As fatigue increases, your upper back may gradually round forward. Eventually, your head drifts farther in front of your body. Before long, the muscles in your neck are working overtime just to keep your eyes looking ahead.
The neck isn’t necessarily the source of the problem. Instead, it’s often the part of the body that’s working hardest to compensate.
This is one of the reasons I’m such a strong advocate for following a structured training plan instead of simply adding more miles or more weight whenever you feel ready.
A common training mistake is changing too many variables at once. Increasing your distance, speed, and ruck weight during the same week makes it almost impossible to determine which change your body is struggling to handle.
Instead, allow your body time to adapt. Build either your mileage, your pace, or your ruck weight—but not all three simultaneously. That simple approach often prevents many overuse problems before they begin.
Myth vs. Reality
Myth: If my neck hurts after rucking, I just need a lighter backpack.
Reality: A lighter backpack may reduce your symptoms temporarily, but if mobility limitations, muscle endurance, training errors, or movement mechanics are the true contributors, the discomfort often returns as your training progresses.
That’s why I encourage people not to focus exclusively on the backpack.
Instead, ask a better question:
“What is my body trying to tell me?”
Once you understand the answer, you’re far more likely to solve the problem for the long term rather than simply managing the symptoms from one ruck to the next.
What I Look for When Someone Comes to Me With Neck Pain After Rucking
One of the questions I hear most often is,
“Can you tell what’s causing my neck pain just by watching me ruck?”
My answer is…
Sometimes.
However, I never like to guess.
One of the principles that has guided my practice for nearly three decades is following the Scientific Method. Instead of making assumptions, I prefer to Test → Treat → Retest.
That process allows me to identify the most likely source of the problem while also determining how quickly your body responds to treatment.
Every person who walks into my office has a different story.
One person may have a previous whiplash injury like I do. Another may have arthritis, a history of shoulder surgery, years of desk work, or simply be new to rucking. Even though two people may describe the same symptom—neck pain after rucking—the reason they’re experiencing that pain can be completely different.
That’s why I don’t believe in handing everyone the same exercise sheet.
Instead, I begin by asking questions.
- When did the pain first start?
- Does it begin during the ruck or afterward?
- Does it occur immediately or the next morning?
- Does it travel into the shoulder, arm, or head?
- What has changed recently in your training?
- Have you increased your mileage, pace, or ruck weight?
- Have you had previous injuries to your neck, shoulders, or back?
Those answers help me develop a working hypothesis before I ever begin the physical examination.
I also look beyond the painful area itself. Over the years, I’ve learned that movement quality and recovery are influenced by much more than muscles and joints. That’s why I developed the SNACS Performance Index™, a framework I use to evaluate five lifestyle factors that affect health, recovery, and performance:
- Sleep
- Nutrition
- Activity
- Chemical-Free Living
- Stress
Even though this article focuses on neck pain after rucking, these five areas often influence how well your body adapts to training, recovers after exercise, and responds to treatment. That’s why I consider both movement and lifestyle when helping someone return to the activities they love.
Then We Start Testing
The movement assessment usually takes between 10 and 20 minutes depending on what we discover.
Rather than focusing only on your neck, I’m evaluating how your entire body works together.
That often includes assessing:
- Cervical mobility
- Thoracic spine mobility
- Shoulder mobility
- Rib cage movement
- Walking mechanics
- Arm swing
- Core stability
- Breathing mechanics
- Backpack fit and load placement
- Muscle tension
- Trigger points
- Previous injury patterns
I’m also looking for asymmetries.
Is one shoulder elevated higher than the other?
Perhaps one arm swings differently.
Maybe one hip rotates more freely.
Or does the head naturally drift forward?
Can your upper back rotate equally to both sides?
Our bodies are remarkably good at compensating. Unfortunately, those compensations often work well—until we ask the body to carry extra weight for several miles.
Then We Treat
Once I identify the areas that appear to be contributing to the problem, treatment begins immediately.
Depending on what I find, treatment may include manual therapy, trigger point release, corrective exercises, mobility drills, breathing strategies, or simple movement corrections.
Sometimes the solution is surprisingly small.
It may involve repositioning the rucksack.
Adjusting the chest strap.
Changing arm swing.
Improving thoracic rotation.
Activating muscles that have become dormant.
Or teaching someone how to relax muscles they’ve unknowingly been holding tense for years.
Then We Retest
This is one of my favorite parts of the entire process.
After treatment, I repeat many of the same movement tests.
Has neck rotation improved?
Does the movement feel easier?
Has the pain decreased?
Has posture changed?
Can the person now perform a movement that was painful only a few minutes earlier?
Those answers tell us whether we’re moving in the right direction.
A Clinical Pearl
One of the reasons I love the Test-Treat-Retest method is that it gives people hope. Instead of waiting weeks to know if they’re improving, they often notice positive changes during the very first visit.
In my practice, approximately 95% of clients experience a 30–50% reduction in symptoms during our first session together. While every person responds differently and no outcome can ever be guaranteed, seeing that immediate change helps people realize that their body is capable of adapting and healing.
More importantly, it shifts the conversation.
Instead of wondering,
“What’s wrong with my neck?”
they begin asking,
“What can I do to keep this improvement going?”
That’s a much more productive question because it moves us away from chasing symptoms and toward addressing the underlying cause.
And that’s ultimately my goal.
I don’t simply want your neck to feel better after today’s ruck.
I want you to understand why it became irritated in the first place so you can continue enjoying walking, hiking, running, and rucking for years to come.
The Hidden Contributors I Commonly See
One of the reasons I enjoy treating neck pain after rucking is that every evaluation becomes a bit like solving a puzzle. Although each person presents differently, I’ve noticed several recurring patterns over the years.
What’s interesting is that many of these issues aren’t actually located in the neck.
Instead, the neck often becomes the “victim” because it’s trying to compensate for problems elsewhere in the body. When you understand those relationships, you stop chasing symptoms and begin addressing the root cause.
Shoulders Doing More Work Than They Should
One of the first things I observe is shoulder position.
Many people spend eight or more hours each day sitting at a computer, driving, or looking down at a phone. Over time, the shoulders gradually round forward and creep upward toward the ears. After a while, that posture simply begins to feel “normal.”
The problem is that your neck muscles never really get a break.
When your shoulders remain elevated, muscles such as the upper trapezius and levator scapulae stay under constant tension. Add a rucksack to that position, and those muscles have to work even harder to stabilize the load.
Instead of carrying the weight efficiently through your torso, your neck begins helping your shoulders do a job they were never designed to do.
One simple coaching cue I often give clients is to imagine gently sliding their shoulder blades into their back pockets rather than shrugging them toward their ears. The goal isn’t to force military posture. Instead, it’s to allow the shoulders to relax while maintaining a tall, confident position.
Poor Thoracic Mobility
If I could identify one area that surprises people the most, it would probably be the upper back.
Most people assume neck pain starts in the neck.
Quite often, I find the opposite.
The thoracic spine—the section of your back where your ribs attach—is designed to rotate and extend. Unfortunately, prolonged sitting, desk work, and modern lifestyles gradually reduce that mobility.
When your upper back becomes stiff, something else has to make up the difference.
Frequently, that’s your neck.
During rucking, your arms naturally swing with every step. That movement should be shared by your shoulders, rib cage, and thoracic spine. If those areas don’t move well, the neck absorbs more rotational stress than it was intended to handle.
I often explain it this way:
Your neck isn’t necessarily moving too much. It may be moving too much because your upper back isn’t moving enough.
That distinction changes how we approach treatment.
Trigger Points That Refer Pain Into the Neck
One of the unique aspects of my practice is my background in Precision Neuromuscular Therapy, which focuses on identifying and treating trigger points.
Trigger points are small, hypersensitive areas within a muscle that can create pain both where they’re located and in entirely different areas of the body.
For example, trigger points in the upper trapezius, sternocleidomastoid, and scalene muscles can refer pain into the neck, the head, the jaw, behind the eye, and even the face.
I’ve had clients convinced they had a serious neck problem when the primary source of their symptoms was actually muscular.
That doesn’t mean trigger points are always the answer.
Joint stiffness, irritated facet joints, cervical discs, nerve irritation, and other conditions can also contribute to neck pain. The key is identifying which tissues are actually responsible instead of assuming every sore neck has the same cause.
Clinical Pearl
One of the biggest mistakes I see is treating only where it hurts. Pain tells us where the body is complaining—not necessarily where the problem began.
Stress and Muscle Guarding
Another contributor that often gets overlooked has nothing to do with backpacks or training plans.
It’s stress.
Many people carry their stress in their neck and shoulders without even realizing it.
Whether the stress comes from work deadlines, family responsibilities, financial concerns, or major life changes, the body’s response is remarkably similar. Muscles tighten. Breathing becomes shallower. The shoulders gradually elevate. Recovery slows.
Even positive stress can have a similar effect.
Training for a Mammoth March, preparing for a long hiking trip, or working toward a new fitness goal places healthy demands on the body. However, when physical stress is layered on top of emotional stress, inadequate sleep, and poor recovery, the muscles often remain in a constant state of guarding.
If you remember the SNACS Performance Index™ I mentioned earlier, Stress and Activity are two of its five pillars. They work together more closely than many people realize.
Regular exercise places healthy stress on the body. However, when physical training is combined with poor sleep, inadequate recovery, work stress, or major life changes, your muscles often remain in a constant state of guarding instead of recovering efficiently.
Simple habits such as diaphragmatic breathing, regular mobility work, walking without weight on recovery days, stretching, prayer, quiet reflection, or practices like yoga and Tai Chi can help calm both the mind and the muscles.
Trying to “Push Through It”
I’ll admit something about myself.
I’m naturally goal-oriented.
When I’m training for an event, I enjoy seeing my mileage increase and checking another workout off my plan. Most runners and ruckers are wired the same way.
That’s why this final contributor is one I see frequently.
People try to push through discomfort because they don’t want to interrupt their progress.
Sometimes that’s appropriate.
Other times, it’s exactly what causes a small issue to become a much bigger one.
One of the easiest ways to avoid overtraining is simply to track what you’re doing.
I personally use a Garmin* watch because it allows me to monitor weekly mileage, training volume, recovery, and other helpful metrics. Whether you use Garmin*, another wearable device, or even a simple notebook, the important thing is having a record of your training.
As a general rule, avoid changing multiple variables at once.
Don’t increase your distance, pace, and ruck weight during the same week. Instead, allow your body time to adapt before asking it to do more.
When I design training plans for clients preparing for longer rucks or endurance events, we’re not just looking at miles or backpack weight.
We’re considering the whole picture.
Strength training improves power and endurance.
Mobility work helps maintain efficient movement.
Recovery sessions allow tissues to adapt.
Sleep and nutrition support healing.
Hydration affects both performance and recovery.
Every variable influences the others.
That’s one of the reasons I enjoy coaching active adults. Rucking may look like nothing more than walking with a weighted backpack, but as your distances increase, it becomes a full-body endurance activity that rewards thoughtful preparation.
The goal isn’t to train harder than everyone else.
The goal is to train wisely enough that you can continue doing what you love for years to come.
Can Neck Pain After Rucking Lead to Headaches?
The short answer is yes.
One of the more frustrating experiences for active adults is finishing a ruck with a tight neck, only to develop a headache later that day or wake up with one the following morning. Because the headache develops after the activity, many people assume they’re dehydrated or simply overdid their workout.
While those factors can certainly contribute, they’re not the only possibilities.
As we discussed earlier, the muscles of the neck and upper shoulders work continuously to support your head while carrying a loaded rucksack. When those muscles become fatigued or irritated, they can refer pain into the head. Likewise, stiff joints in the upper cervical spine may also contribute to headache symptoms.
These headaches are commonly referred to as cervicogenic headaches, which simply means the headache originates from structures in the neck rather than inside the head itself.
Unlike migraines, cervicogenic headaches are often associated with neck stiffness or pain and may become worse when turning your head or maintaining the same posture for an extended period.
Clinical Pearl
In my experience, many people treat the headache without ever addressing the neck that caused it. If the source of the problem isn’t corrected, the headaches often continue to return.
That doesn’t mean every headache is caused by the neck.
Migraines, tension-type headaches, sinus headaches, dehydration, medication side effects, high blood pressure, and many other medical conditions can also produce headache symptoms. That’s one reason a thorough evaluation is so important. The goal isn’t simply to label the headache—it’s to understand why it’s occurring.
Because cervicogenic headaches are a topic all their own, I’ll be covering them in much greater detail in a future article, including how they’re diagnosed, common misconceptions, and when physical therapy may be an appropriate treatment option.
For now, remember this:
If your headaches consistently develop after rucking and are accompanied by neck stiffness or discomfort, your neck deserves just as much attention as your head.
When Neck Pain Is More Than Normal Muscle Soreness
Whenever you begin a new exercise program or increase your training load, it’s completely normal to experience some muscle soreness.
In fact, Delayed Onset Muscle Soreness (DOMS) is a healthy response to asking your muscles to do more than they’re accustomed to doing. That soreness typically develops within 12 to 24 hours after exercise, peaks around 24 to 48 hours, and gradually resolves within about 72 hours.
As a general rule, if your soreness lasts longer than three days, your body may be telling you that your recent training exceeded its current capacity.
I also encourage my athletes and clients to use a simple pain scale.
If your discomfort is 4 out of 10 or less, and it feels like generalized muscle soreness, it’s often reasonable to continue moving while monitoring your symptoms. Gentle walking, mobility work, and active recovery frequently help muscles recover more comfortably.
However, once pain climbs above that level—or begins changing in character—it’s time to pay closer attention.
Soreness is usually described as dull, achy, or tight.
Pain is different.
Sharp pain.
Burning pain.
Electrical sensations.
Numbness.
Tingling.
Weakness.
Those symptoms suggest something more than normal post-exercise soreness and shouldn’t simply be pushed through.
Know the Red Flags
Seek prompt medical evaluation if your neck pain is accompanied by:
- Numbness or tingling into the arm or hand
- Progressive weakness
- Loss of coordination or balance
- Severe dizziness
- A sudden or severe headache unlike one you’ve experienced before
- Chest pain or shortness of breath
- Symptoms following significant trauma or a fall
- Pain that continues worsening instead of gradually improving over several days
Fortunately, these situations are much less common than muscle fatigue or overtraining. Nevertheless, they’re important to recognize because they require a different level of medical attention.
One of the most valuable skills any runner or rucker can develop is learning to distinguish between normal training fatigue and pain that signals something isn’t right.
Your body is remarkably adaptable.
It also communicates remarkably well.
The challenge is learning how to listen.
What You Can Do Before Your Next Ruck
By now, you’ve probably realized there isn’t a single cause of neck pain after rucking. That’s actually good news because it means there are multiple opportunities to reduce your symptoms and improve your experience.
Rather than asking, “What’s wrong with my neck?” I encourage you to ask, “What can I change before my next ruck?”
Over the years, both through my own training and working with clients, I’ve found that a few thoughtful adjustments often make a much bigger difference than simply pushing through the discomfort.
Start With Your Equipment
One lesson I learned personally was that quality equipment matters.
When I upgraded from an ordinary backpack to a properly fitted rucksack, I immediately noticed an improvement in comfort. Years later, adding a chest strap made an even bigger difference during my longer training sessions.
Good equipment doesn’t eliminate every problem, but it does remove unnecessary obstacles.
If you’re serious about rucking, consider asking yourself:
- Does my rucksack fit my body properly?
- Is the weight distributed evenly?
- Am I using the chest strap correctly?
- Would trekking poles reduce fatigue during longer distances or uneven terrain?
I especially appreciate trekking poles during longer events because they help distribute the workload throughout the body instead of allowing everything to accumulate in the shoulders and neck.
Review Your Training Load Honestly
One of the most common mistakes I see isn’t poor posture.
It’s poor progression.
Whenever symptoms develop, I encourage clients to look back over the previous two or three weeks instead of focusing only on their most recent workout.
Ask yourself:
- Did I increase my mileage too quickly?
- Did I add weight and distance during the same week?
- Did I increase my pace while also increasing my pack weight?
- Have I given my body enough time to adapt?
Your body doesn’t know what your training plan says.
It only knows the stress you’ve asked it to handle.
Although the often-quoted “10% rule” can provide a reasonable starting point, every person adapts differently. Depending on your age, training history, body size, recovery, and previous injuries, your progression may need to be slower—or occasionally faster.
The goal isn’t to follow someone else’s training plan perfectly.
The goal is to build a plan your body can consistently tolerate.
Build Fitness Before Adding More Weight
One principle I emphasize with new ruckers is simple:
Earn the right to carry more weight.
If walking three miles without a backpack leaves you exhausted, adding a 20-pound rucksack won’t improve your conditioning—it will simply expose the areas that aren’t ready for that level of demand.
Instead, establish a strong walking foundation first.
Then gradually increase one variable at a time.
As your endurance improves, your body becomes much more capable of handling additional weight while maintaining efficient movement.
Don’t Forget the Recovery Side of Training
Many people think training only happens during exercise.
I disagree.
Training also happens while you recover.
Ask yourself:
- Am I sleeping enough to allow my muscles to recover?
- Am I staying hydrated throughout the day—not just during my ruck?
- Am I eating enough protein and carbohydrates to support my activity level?
- Have I scheduled recovery days into my week?
- What’s my current stress level outside of exercise?
These questions tie directly into the SNACS Performance Index™, which looks at the lifestyle habits that influence how well your body performs and recovers.
You can have the perfect training plan, but if your sleep is poor, your stress is high, and your recovery is inadequate, your body will eventually let you know.
Think Long-Term, Not Just About Today’s Workout
One of the things I enjoy most about coaching runners and ruckers is helping them prepare for goals they once thought were out of reach.
Whether that’s completing your first three-mile ruck, finishing a Mammoth March, or simply walking pain-free with your family, success rarely comes from one perfect workout.
It comes from hundreds of smart decisions made over time.
Those decisions include choosing appropriate equipment, progressing gradually, prioritizing recovery, strength training consistently, improving mobility, and listening to your body’s feedback instead of ignoring it.
Clinical Pearl
The strongest athletes aren’t always the ones who train the hardest. They’re often the ones who recover the best and adjust their training before a small problem becomes a season-ending injury.
That’s the mindset I encourage every runner and rucker to develop.
Because the ultimate goal isn’t simply completing your next ruck.
It’s being able to enjoy this sport for many years to come.
The Goal Isn’t Just Less Pain—It’s Enjoying Rucking Again
When I talk with runners, ruckers, and active adults, I rarely hear someone say,
“My goal is to have perfect posture.”
Or,
“I just want my neck to stop hurting.”
Those may be immediate concerns, but they’re almost never the real goal.
At the end of the day, most people simply want to keep doing the activities they love.
Maybe that’s completing another Mammoth March.
Perhaps it’s hiking with a spouse on vacation.
For others, it’s walking the dog without worrying about how they’ll feel the next morning.
Or maybe it’s finishing a charity ruck, exploring a national park, or simply enjoying the outdoors without pain stealing the experience.
That’s the goal.
Pain is simply the obstacle standing in the way.
One of the things I’ve learned from both treating patients and experiencing my own setbacks is that pain has a way of changing more than just the body.
It changes confidence.
After you’ve experienced neck pain a few times, it’s easy to start wondering:
“What if it happens again?”
“Should I skip today’s workout?”
“Maybe my body just isn’t built for this.”
Those thoughts can become just as limiting as the physical discomfort itself.
Over the years, I’ve seen people become hesitant to increase their mileage.
Some runners shorten their stride because they’re afraid of aggravating a previous injury.
Others stop carrying backpacks altogether because they assume pain is simply part of getting older.
I don’t believe that has to be the story.
Certainly, there are times when we need to modify our activities while the body heals. There are also situations where arthritis, previous injuries, or other medical conditions require us to adjust our expectations.
However, in many cases, improving movement quality, building strength, progressing training wisely, and addressing the underlying contributors allows people to return to activities they thought they had to give up.
That’s one of the most rewarding parts of my profession.
There is something incredibly satisfying about watching frustration turn into confidence.
Seeing someone who was nervous about carrying a backpack complete a long ruck with a smile.
Watching a client realize they can turn their head freely again.
Hearing someone say,
“I didn’t think I’d ever be able to do this again.”
Those moments never get old.
They’re reminders that physical therapy isn’t just about reducing pain.
It’s about restoring possibility.
Clinical Pearl
Pain relief is an important milestone, but it isn’t the finish line. My goal is to help people build a body that’s resilient enough to continue doing the activities they love with confidence.
For me, rucking has become much more than exercise.
It’s an opportunity to spend time outdoors.
For me, rucking has become much more than exercise.
It’s an opportunity to challenge myself physically, clear my mind, spend time in prayer, think through life’s challenges, and enjoy God’s creation.
I want other people to experience those same benefits without feeling limited by pain or uncertainty.
If neck pain has been taking the enjoyment out of your walks, hikes, or rucks, remember this:
Your body isn’t working against you.
It’s communicating with you.
When you learn to listen to what it’s saying—and respond appropriately—you often discover that the obstacle isn’t as permanent as it first appeared.
Sometimes the solution isn’t simply carrying less weight.
Sometimes it’s helping your body carry life a little more efficiently.
Frequently Asked Questions
Why does my neck hurt several hours after a ruck?
Neck pain that develops several hours after a ruck—or even the next morning—is often the result of muscle fatigue rather than an injury that occurred during your walk. As your muscles tire, your posture and movement patterns can gradually change without you realizing it. The additional workload placed on your neck and shoulders may not become noticeable until your body begins to recover.
Delayed muscle soreness is common after exercise. However, if your neck pain becomes progressively worse, lasts longer than 72 hours, or is accompanied by numbness, tingling, weakness, or severe headaches, it’s worth having the problem evaluated to determine whether something more than normal muscle fatigue is contributing to your symptoms.
Can my backpack really cause neck pain?
Yes—but it isn’t always the primary cause.
A poorly fitted backpack, uneven load distribution, or carrying more weight than your body is prepared for can certainly contribute to neck pain. However, as I discussed throughout this article, I often find that the backpack simply exposes underlying issues such as limited mobility, muscle imbalances, previous injuries, poor endurance, or training errors.
Before replacing your backpack, it’s worth asking whether your body is prepared to carry the load you’re asking it to manage.
Should I stop rucking if my neck hurts?
Not necessarily.
If your discomfort feels like mild muscle soreness and remains at a low level, reducing your distance, decreasing your ruck weight, or allowing an extra recovery day may be all that’s needed. Gentle movement often helps muscles recover better than complete rest.
On the other hand, sharp pain, increasing symptoms, numbness, tingling, weakness, dizziness, or pain that changes your walking mechanics should not be ignored. In those situations, it’s wise to stop your workout and determine what’s causing the symptoms before continuing your training.
The goal isn’t simply to push through pain—it’s to train consistently without creating a larger setback.
Can trigger points cause neck pain after rucking?
Absolutely.
Trigger points in muscles such as the upper trapezius, sternocleidomastoid, levator scapulae, and scalenes can all contribute to neck pain after rucking. They may also refer pain into the head, jaw, face, or shoulder, making the symptoms feel more widespread than they actually are.
However, trigger points are only one possible contributor. Joint stiffness, irritated nerves, previous injuries, poor movement mechanics, and training progression should also be considered during a comprehensive evaluation.
Can physical therapy help neck pain from rucking?
In many cases, yes.
One of the advantages of working with a physical therapist who understands runners and ruckers is that the evaluation goes beyond simply treating the painful area. Instead, we look at how your entire body moves, how your training has progressed, and what factors may be contributing to the problem.
My goal isn’t simply to reduce your neck pain. It’s to identify why your symptoms developed so you can return to rucking with greater confidence and reduce the likelihood of the problem returning.
How heavy should my backpack be?
There isn’t one “perfect” weight for everyone.
The appropriate weight depends on your age, training history, current fitness level, previous injuries, the terrain you’ll be covering, and your overall goals. Some organized rucking events also have minimum weight requirements for certain divisions, so your training should reflect the demands of the event you’re preparing for.
For most beginners, I recommend establishing a comfortable walking routine before adding weight. Once your body adapts to the distance, gradually increase your ruck weight while avoiding changes to multiple training variables at the same time.
Remember, carrying more weight doesn’t automatically make you stronger.
Training consistently and progressing wisely does.
Is neck pain after rucking just part of getting older?
I hear this comment quite often, and my answer is usually the same:
Growing older is inevitable. Living with unnecessary pain isn’t.
Our bodies naturally change with age. Recovery may take a little longer, and previous injuries may influence how we train. However, many people assume their discomfort is simply something they have to accept, when in reality there are often modifiable factors contributing to their symptoms.
I’ve worked with many active adults who believed neck pain was just part of aging, only to discover that improving mobility, strength, posture, training progression, and recovery significantly reduced their symptoms.
Don’t let your birth certificate determine what’s possible. Let your body tell the story.
Final Thoughts
One of the reasons I enjoy working with runners, ruckers, and active adults is that they’re motivated. They aren’t looking for permission to sit on the sidelines—they’re looking for a way to keep moving.
If that’s you, I want to encourage you with this thought:
Neck pain after rucking doesn’t automatically mean you have to stop rucking.
More often than not, it’s your body’s way of asking you to pay attention to something that can be improved.
Sometimes it’s your equipment.
Other times, it’s your training plan.
In many cases, mobility, strength, recovery, or stress play an important role.
Often, it’s a combination of several factors.
The good news is that your body is remarkably adaptable.
When you identify the root cause instead of simply chasing symptoms, you can often return to the activities you love with greater confidence and a better understanding of how your body works.
As both a physical therapist and a fellow rucker, I’ve experienced firsthand how small changes can make a significant difference. I’ve also had the privilege of helping many active adults overcome setbacks they thought would permanently limit their ability to stay active.
That’s why I believe movement is one of the greatest investments you can make in your long-term health.
Whether your goal is completing your first three-mile ruck, preparing for a Mammoth March, hiking with your family, or simply walking without discomfort, you don’t have to figure it out alone.
If neck pain after rucking has been limiting your progress, I encourage you to start by understanding why it’s happening.
Sometimes the smallest adjustment becomes the turning point that allows you to enjoy rucking again.
