Runner’s hip is an umbrella term for several overuse injuries that cause pain in or around the hip joint during or after running. It most commonly refers to greater trochanteric pain syndrome (pain on the outer hip), but can also involve hip labral tears, hip impingement, or irritation of the tendons and muscles surrounding the pelvis. Hip injuries account for about 7% of all running-related injuries, making the hip the third most common site of pain after the foot and knee.
Because “runner’s hip” isn’t a single diagnosis, understanding where your pain is and what triggers it is the fastest way to figure out what’s going on and what to do about it.
Common Conditions Behind Runner’s Hip
Greater Trochanteric Pain Syndrome
This is the most frequent cause of outer hip pain in runners. The greater trochanter is the bony point you can feel on the outside of your hip, and the tendons and fluid-filled sacs (bursae) around it can become inflamed from repetitive stress. You’ll typically feel a sharp pain on the side of your hip that gradually turns into a deeper ache. It often worsens when getting out of a chair, climbing stairs, lying on the affected side at night, or sitting for long periods. Some people also notice stiffness, swelling, or a clicking sensation in the hip.
Hip Labral Tears and Impingement
The labrum is a ring of cartilage that lines the rim of your hip socket, helping to keep the joint stable. Subtle asymmetries in the hip joint can cause this cartilage to get pinched between the ball and socket during repetitive motions like running, eventually leading to a tear. This condition, often paired with femoroacetabular impingement (FAI), tends to produce a deep, catching pain in the groin or front of the hip rather than the outer side. You might notice a locking or clicking feeling during certain movements, particularly when bringing the knee up toward the chest or rotating the leg inward.
Hip Flexor and Piriformis Issues
The hip flexors (muscles at the front of the hip) and the piriformis (a small muscle deep in the buttock that crosses over the sciatic nerve) are commonly overused in runners. When these muscles become tight or strained, they can refer pain to the front of the hip, deep in the buttock, or even down the leg. The piriformis in particular can become very tight if it isn’t regularly stretched and strengthened, sometimes mimicking sciatic nerve pain.
Why Running Causes Hip Pain
The underlying issue for most runners with hip pain is a combination of repetitive impact and muscle weakness, particularly in the gluteus medius. This muscle sits on the outer hip and is responsible for keeping your pelvis level with every stride. When it’s weak, the pelvis tilts and one side dips lower than the other during your gait cycle. This asymmetry, sometimes called “hip drop,” forces surrounding structures to compensate, overloading tendons, bursae, and cartilage over hundreds or thousands of repetitions per run.
Imbalances in strength and flexibility between the left and right side, poor running form, sudden increases in mileage, and inadequate recovery time all contribute. Runners training for marathons or half marathons face particularly high risk: between 29% and 43% of runners preparing for these distances develop a running-related injury during their training cycle.
How Runner’s Hip Is Diagnosed
Diagnosis starts with a physical exam. Your provider will ask you to point to exactly where the pain is, press around the hip area, and move your hip and leg through different positions while you lie on an exam table. They may also watch you walk, sit down, and stand up, and measure the length of each leg to check for asymmetries.
One common test is the FABER test, where you lie on your back and place your leg in a figure-4 position while the examiner gently presses down on the knee. Depending on where pain shows up during this maneuver, it can point toward different causes: groin pain suggests a hip flexor issue, pain deep in the joint suggests impingement or a labral tear, and pain at the back or side of the hip points toward joint dysfunction.
If the physical exam doesn’t paint a clear picture, imaging may follow. X-rays can rule out bone problems, while an MRI or ultrasound can reveal soft tissue damage like labral tears, tendon inflammation, or bursitis.
Treatment and Recovery
Most cases of runner’s hip improve with conservative treatment. The typical recovery window for the most common form, greater trochanteric pain syndrome, is a few weeks to a few months of rest and targeted rehabilitation. The cornerstone of treatment is a structured exercise program focusing on the muscles around the pelvis: the gluteus medius, gluteus maximus, hamstrings, hip adductors, abductors, and piriformis. A standard conditioning program runs 4 to 6 weeks, performed 2 to 3 days per week.
A systematic review comparing exercise to steroid injections for greater trochanteric pain syndrome found that exercise produces better long-term outcomes. While an injection may reduce pain faster in the short term, patients who followed an exercise program were more likely to experience meaningful, lasting improvement. This makes rehabilitation the preferred first-line approach for most runners.
Your return to running will depend on how severe the injury is and how consistently you follow a rehab program. For mild cases, you may be able to continue running at reduced volume while rehabbing. For more significant pain, a complete break from running is usually necessary before gradually building back. If symptoms persist beyond six months despite conservative treatment, surgical options like removing an inflamed bursa may be considered.
Exercises That Protect Against Hip Injuries
Runners who are strongest in their core, pelvis, gluteus medius, and hip flexors tend to get injured less and run faster. They rely more on their glutes and hip flexors for propulsion rather than overloading smaller muscles in the legs. Two days of strength training per week is enough to target the muscles runners commonly neglect, using three sets of 10 to 15 repetitions per muscle group as a baseline.
Effective exercises include:
- Lateral leg raises and clamshells: directly strengthen the hip abductors that stabilize the pelvis during running
- Single-leg Romanian deadlifts: work the hamstrings, glutes, lower back, and piriformis
- Single-leg (pistol) squats: build quad, glute, and core strength while challenging single-leg balance
- Bird dogs: target core and glute stability simultaneously
- Hip hikes: specifically train the pelvis to stay level, counteracting hip drop
- Hamstring chair bridges: strengthen the posterior chain that supports the hip
Stretching matters too. The piriformis and hip flexors are especially prone to tightening in runners. Pigeon pose and a seated piriformis stretch (crossing one ankle over the opposite knee and leaning forward) help keep these muscles from becoming chronically shortened. Incorporating both strengthening and stretching into your routine addresses the two most controllable risk factors for runner’s hip: weakness and inflexibility around the pelvis.
