Trail running stacks the demands of road running on top of unstable, hilly terrain: every footstep has to adapt to the ground in real time, and descents absorb forces far greater than a road run. That’s what makes it a demanding sport for the ankles and knees. HOPP was designed by FIFA-certified sports physios to help you understand your trail running injury and get back to it without getting hurt a second time.
The most common trail-running injuries
Rugged terrain and long descents expose you to specific injuries, often different from those seen in road running.
The most common, and why
Ankle sprain
— trail running’s #1 injury, linked to unstable terrain.Iliotibial band syndrome
— very common on long descents that load the outer knee.Achilles tendinopathy
— tendon overuse from repeated elevation gain.Plantar fasciitis
— overuse linked to uneven terrain and long distances.Shin splints
— common when volume or elevation gain is increased too quickly.

Not sure exactly what you have?
Take the HOPP test and get a clear answer about your injury.
Cause #1: poorly managed elevation gain and terrain
Unsuitable shoes, lack of eccentric strengthening, imperfect downhill technique: these factors play a role, but the most common cause of trail-running injuries lies elsewhere. In the vast majority of cases, it’s elevation gain or distance increased too quickly, exceeding the body’s ability to adapt.
The most common pacing mistakes
Increasing uphill or downhill elevation too quickly
Stacking long outings without enough recovery
Neglecting eccentric quadriceps strengthening before a race with elevation gain
Returning after an injury without readjusting terrain difficulty
HOPP physio tip
before blaming your shoes or the terrain, the first question to ask yourself is almost always the same: have I increased my elevation gain or distance too quickly? That’s the factor most often at fault, and also the easiest to fix once identified.
The risks of doing nothing
Continuing to stack outings without understanding what’s going on is never a good strategy. Without proper care, a trail-running injury almost always follows the same script.
What you risk without proper care
An injury that gets worse if you keep running without adjusting your load or the terrain
A longer recovery period than with prompt care
A higher risk of relapse on your return, if the cause hasn’t been treated
HOPP takes care of every trail runner profile
A seasoned ridge runner, a regular on Sunday forest outings, someone discovering trail running after years on the road: every trail runner profile has different needs, but none is left out by HOPP.
The profiles HOPP supports
How HOPP supports you, day after day
Since poorly paced elevation gain is the leading cause of trail-running injuries, it’s also the first thing HOPP helps you manage better. Every morning, you indicate how you feel, and your programme adjusts accordingly: a bit more load if all is well, a bit less if the area is complaining. The programme helps you find the right balance between distance, elevation gain and recovery, day after day.

HOPP is an injury information tool designed by sports physiotherapists. It doesn’t replace a doctor’s opinion.
Frequently asked questions
Does HOPP replace a medical consultation?
No. HOPP is an injury information tool designed by sports physiotherapists, it doesn’t replace a doctor’s opinion. It gives you clear, quick guidance to understand your situation and know how to act, and directs you to a professional if needed.
Do I need to stop trail running completely during the programme?
Not necessarily. The programme adapts to your injury and how you feel each day: depending on the case, you may keep running on flat terrain or road while elevation load is temporarily reduced, rather than stopping completely.
I’m just starting out in trail running, is HOPP right for me?
Yes. The programme is calibrated to your actual practice, whether you come from road running or you’re completely new to off-road running. It’s not designed only for experienced trail runners.
How long before I feel an improvement?
It depends on the injury and how long you’ve had it. You get a first clear explanation in 3 minutes, then the care programme gives you a realistic return trajectory, adjusted every day based on how you feel.
What if my condition doesn’t improve with the programme?
You can talk it through by teleconsultation with an expert sports physiotherapist to review your situation. HOPP also directs you to a medical consultation if your symptoms require it.
Is the 3-minute test really free?
Yes, the test that explains your injury is free and with no commitment. You then freely choose whether you want to start a suitable care programme.
