Member Question:
“What is the importance of stretching before and after a run, and can this be incorporated into your run?”
Kerrie – Level 4 Member of FLOCK
A great question from Kerrie – Trail running asks more of your body than road running: uneven ground, cambers, steep climbs, quick descents, and constant micro-adjustments through your feet, ankles, hips, and core. Stretching won’t “injury-proof” you on its own, but smart pre- and post-run mobility can help you move better on the trails, feel less stiff, and recover faster between sessions.
First: stretching vs mobility ( and why it matters)
When runners say “stretching,” they often mean two different things:
- Dynamic mobility (before a run): controlled movement through range of motion to warm tissues and switch muscles on.
- Static stretching (after a run): longer holds to downshift, restore length, and reduce that tight, shortened feeling.
For trail running, that distinction is key. Before you run, you want to feel springy and switched on — not relaxed and floppy.
Why pre-run mobility is especially important for trail running
On trails, your body needs to react quickly and repeatedly. A short warm-up can help:
- Improve ankle and hip mobility for uneven surfaces and steep gradients
- Activate glutes and calves for climbing power and stable landings
- Prepare your feet and lower legs for constant changes in angle and impact
- Reduce the “first 10 minutes feel awful” effect by raising temperature and blood flow
A simple 6-8 minute pre-run routine (trail-friendly)
Do this before your run (or at the trailhead). Keep it smooth and controlled.
- Brisk walk or easy jog – 2 minutes
- Ankle circles + ankle rocks – 30 seconds each side
- Leg swings (front/back, then side/side) – 10 each direction per leg
- Walking lunges with a reach – 8–10 steps
- Glute activation (bodyweight squats or hip hinges) – 10–12 reps
- Calf raises (slow up, slow down) – 10 reps
- High knees or skipping – 20–30 seconds
If you’re heading into a hard session (hills/intervals), add 2 x 20 seconds of faster strides on flat ground.
Why post-run stretching helps (even if you “feel fine”)
After a trail run, your calves, hips, and feet often take a beating — especially from descents. Post-run stretching can help:
- Bring your nervous system down (great if you finish wired)
- Restore range of motion after lots of climbing/descending
- Reduce next-day stiffness (particularly calves, hip flexors, and glutes)
- Spot niggles early — tightness in one area can be a useful signal
A calm 8-10 minute post-run stretch routine
Hold each stretch 30–45 seconds, breathing slowly. Aim for “strong but not painful.”
- Calf stretch (straight knee) – targets gastrocnemius
- Soleus stretch (bent knee calf stretch) – targets deeper calf
- Hip flexor stretch – especially if you’ve climbed a lot
- Glute stretch (figure-4 or lying glute stretch)
- Hamstring stretch – gentle, not aggressive
- Quad stretch – keep knees close together
- Foot/plantar fascia release – roll a ball under the arch for 60–90 seconds each foot
If you only have time for three: calves, hip flexors, glutes.
Common mistakes (and what to do instead)
- Static stretching before you run Save long holds for after. Before a run, use dynamic mobility.
- Stretching cold Even post-run, do your stretches after a short walk and a sip of water — not the second you stop.
- Forcing range of motion Trail running needs control, not extreme flexibility. Gentle consistency beats aggressive stretching.
- Ignoring strength work Tightness is often your body asking for stability. Pair stretching with simple strength (calf raises, split squats, hip hinges) a couple of times per week.
How often should I stretch
A realistic plan that works for most runners:
- Before every trail run: 5–8 minutes of dynamic mobility
- After 2–4 runs per week: 8–10 minutes of static stretching
- On rest days: 10–15 minutes of mobility if you’re stiff or desk-bound
Consistency matters more than the “perfect” routine.
Trail-specific tips (for confidence and injury prevention)
- Descending days = calf and quad care. Downhills load your calves and quads heavily. Prioritise them post-run.
- If you’re new to trails, warm up longer. Your ankles and feet are learning new demands.
- If you feel recurring tightness in one spot, don’t just stretch it. Check footwear, training load, and consider adding strength and balance work.
The takeaway
For trail runners, pre-run mobility is about readiness and stability, and post-run stretching is about recovery and keeping your movement options open. Keep it short, repeatable, and tailored to what the trails demand most: ankles, calves, hips, and glutes.
