Stretches for Runners: Pre and Post-Run Routine

Dynamic stretching (moving stretches) before running — static stretching (held positions) after running. Static stretching cold muscles before a run temporarily reduces muscle-tendon stiffness and has not been shown to prevent injury. Dynamic movements before running (leg swings, high knees, hip circles) prepare the joints and muscles for the running motion without impairment. Static stretching is most effective on warm muscles immediately after a run, when tissue is most pliable and flexibility gains are most accessible.

10 minutes of post-run static stretching is sufficient for most runners. Each stretch should be held for 30–45 seconds (not less — shorter durations produce minimal flexibility gains). Prioritise calves, hip flexors, hamstrings, and glutes — the four muscle groups most frequently tight in runners and most directly linked to common running injuries. Stretching for longer (20–30 minutes) produces greater gains but is impractical for most training schedules — consistency over weeks matters more than session length.

Static stretching alone has limited evidence for injury prevention. The benefit of a post-run stretching routine is primarily through gradual flexibility improvement over weeks and months, which reduces tissue stress at end-range of motion during running. The more impactful injury prevention measures are: following the 10% mileage increase rule, strength training hip abductors and calves, and replacing shoes at 600–800 km. Stretching is a useful complement but not a substitute for these primary interventions.

Stretching on rest days (active recovery stretching) can accelerate flexibility gains compared to stretching only on running days, particularly for very tight muscle groups. A 5–10 minute routine of the static stretches from this guide on non-running days is beneficial, particularly if you spend significant time sitting. The most important muscles to address on rest days: hip flexors (shortened by prolonged sitting) and calves (often tight from running volume). Yoga or Pilates sessions are excellent structured rest-day flexibility work for runners.

The most comprehensive calf stretch targets both the gastrocnemius (the larger, more superficial calf muscle) and the soleus (deeper, more relevant to Achilles and plantar fascia health) separately. For gastrocnemius: stand facing a wall, back leg straight, heel flat on the ground, lean forward. For soleus: same position but with the back knee slightly bent. Hold each position 30–45 seconds per leg. Both are needed because each has a separate attachment and different running-related injury associations — the gastrocnemius to knee-related issues; the soleus to Achilles and plantar fascia.

No — foam rolling and stretching address different tissue properties. Foam rolling (self-myofascial release) provides compressive load to the soft tissue, temporarily reducing perceived tightness and improving short-term range of motion through neurological mechanisms. Stretching improves actual muscle-tendon length through mechanical creep over time. Both are useful: foam roll first (60–90 seconds per area) to reduce post-run tightness, then static stretch the same areas to work on sustained range of motion improvement. Neither fully substitutes for the other.

Post-run stiffness (delayed onset muscle soreness, or DOMS) results from microscopic muscle damage from the eccentric loading of running — particularly after long runs, downhill running, or new training stimuli. Stretching reduces it somewhat but does not eliminate it. DOMS typically peaks 24–48 hours after a hard session and resolves within 72 hours. Strategies that reduce DOMS: adequate protein intake post-run, active recovery walking or light cycling the following day, and cold water immersion. Stiffness from consistent training gradually diminishes as the body adapts over 4–8 weeks.

Depends on the injury. For Achilles tendinopathy: gentle calf stretching (particularly soleus) is part of standard rehabilitation. For plantar fasciitis: calf and plantar fascia stretching is recommended. For runner's knee: hip flexor and IT band stretching combined with hip strengthening. For shin splints: rest is primary; gentle calf stretching may help. For acute injuries (stress fracture, tendon rupture): do not stretch until medically cleared. Always consult a physiotherapist before using stretching as self-treatment for a diagnosed injury — some injury states require load (strengthening) rather than lengthening (stretching) as the primary intervention.
