It’s mile eight, or two hours into a climb up Lookout Mountain, and there it is again — that sharp pinch in the front of your hip. It fades when you back off, so you keep training around it. Deep squats feel blocked. Sitting through a movie makes it ache. Sound familiar?
That pattern has a name: hip impingement, or femoroacetabular impingement (FAI). It’s one of the most common hip complaints we see in endurance athletes at Lakeside Spine and Injury Center — and the athletes who address it early do dramatically better than the ones who train through it for a year first.
What Hip Impingement Actually Is
Your hip is a ball-and-socket joint. Impingement happens when the ball and the rim of the socket make contact too early in the range of motion — pinching the labrum (the cartilage ring around the socket) and the soft tissue between them.
Sometimes bone shape plays a role. But here’s the part that matters for athletes: how your hip is shaped is only half the story — how it moves is the other half. Plenty of people with “impingement-shaped” hips on imaging have zero pain. Stiffness, muscle imbalance, and repetitive loading in one narrow range are usually what turn anatomy into symptoms.
Why Runners and Cyclists Are Prime Candidates
Running and cycling share a defining trait: thousands of repetitions of hip flexion, in a straight line, with almost no rotation or side-to-side movement.
- Cyclists spend hours with the hip flexed and never fully extended — an aggressive aero position keeps the joint pinched near its impingement zone for the entire ride, while the hip flexors adaptively shorten.
- Runners load the hip with several times body weight, stride after stride. If the glutes aren’t controlling the femur well — very common in runners who also sit at a desk all day — the ball rides forward in the socket and pinches at the front.
- Both tend to be strong in one plane and underdeveloped in rotation and abduction — exactly the movements that keep a hip centered and healthy.
Add Colorado’s long climbing rides and trail miles, and the recipe is complete: a hip that’s overworked in one groove and neglected everywhere else.
The Early Warning Signs Worth Taking Seriously
- A pinching or sharp catch in the groin with deep hip flexion — squats, hill climbing, aero position, bringing the knee to the chest.
- The “C-sign” — cupping your hand around the side of your hip to describe where it hurts, because the pain feels deep rather than on the surface.
- Ache after sitting, especially in low seats or long car rides.
- Lost internal rotation — your knee doesn’t drop inward as far on one side, or pivoting feels blocked.
- Clicking or catching that’s starting to come with discomfort rather than just noise.
Ignore these long enough and the irritation compounds: the labrum takes more abuse, surrounding muscles guard harder, and your stride or pedal stroke quietly reorganizes around the problem — which is often when knee and low back issues show up as collateral damage. That chain reaction works both ways; we covered it in our post on how chiropractic fits into sports rehab.
What to Do Before It Gets Worse
The good news: caught early, impingement-type hip pain usually responds well to conservative care. The plan we build at Lakeside typically has four parts:
1. Restore the motion you’ve lost
Joint mobilization for the hip capsule and soft tissue therapy for the hip flexors, TFL, adductors, and glutes. Dr. Andrew Allen, DC leans on his soft-tissue expertise heavily here — releasing the tissues that are dragging the ball forward in the socket buys back pain-free range faster than stretching alone.
2. Strengthen what centers the joint
Glute med and deep rotator work, split-stance and lateral movement, controlled rotation — the planes your sport skips. A hip that’s strong in all directions stops pinching in one.
3. Modify — don’t abandon — your training
Most athletes keep training while we work. A slightly higher handlebar stack or saddle tweak, shorter crank arms, a cadence bump, temporarily swapping deep-flexion strength work for hinge patterns — small changes that take the joint out of its angry zone while it calms down.
4. Reassess honestly
If a hip doesn’t respond the way it should, or exam findings suggest significant labral involvement, we say so and coordinate imaging or a specialist referral. True mechanical locking, giving way, or constant night pain are signs to get evaluated promptly rather than pushing through another training block.
Built for Colorado Athletes
This is exactly the kind of problem our athlete chiropractic care in Wheat Ridge is built for: keep you moving, fix the mechanics driving the irritation, and get ahead of the injury instead of chasing it. Whether you’re training for a fall marathon or logging base miles for ski season, the earlier we see the hip, the more options you have.
Feel That Pinch? Let’s Look at It Now, Not Next Season
A hip that pinches at mile eight this month can be a hip that aches at mile one by spring. Dr. Allen offers a free 30-minute evaluation — movement testing, hands-on assessment, and a straight answer about what’s going on. Call (303) 351-0744 or book your free evaluation online.
