Use mobility work before you run and save static stretching for after. Mobility means moving a joint through usable range under control; static stretching means holding a muscle at length. Dynamic moves rehearse running form while muscles warm up. Static holds work better later, when warm legs can gain range without hurting the run ahead.

What works best before a run?
Start with 5-10 minutes of light jogging plus dynamic mobility. Mayo Clinic News Network describes the warm-up as controlled leg swings, lunges and marches that raise muscle temperature and rehearse mechanics dynamic stretching guidance.
Use moves that look like running, only larger and slower. Good options include walking lunges, leg swings, high marches and easy skips. Keep motion smooth and stop before fatigue.
- Jog lightly for 5-10 minutes
- Add leg swings, lunges and marches
- Keep movements controlled, without bouncing
- Stop the move if it causes pain
When does static stretching help?
Static stretching helps most after a run, when muscles are warm. Mayo Clinic advises holding major leg muscles to mild tension for about 30 seconds, and 60 seconds for tight areas post-run stretching guidance.
Target calves, quadriceps, hamstrings, hip flexors and glutes. Breathe normally and ease into mild tension, not sharp pull. Repeat tight spots rather than forcing one long hold.
What does pre-run static holding cost?
Pre-run static holds can make the same pace cost more energy. A 2015 review in Strength and Conditioning Journal concluded that acute static stretching before running decreases running economy running-economy review.
That means runners use more oxygen at the same submaximal speed. A Florida State study found trained distance runners became about 5 percent less economical and covered 3 percent less distance after pre-run static stretching. For a race or hard workout, that penalty matters.
Can stretching prevent injury or soreness?
Stretching before running cannot be claimed to prevent injury. A 2011 Cochrane review found the evidence base very weak, with few low-bias trials on soft-tissue injury prevention in runners.
Expectations for soreness should also stay low. A separate Cochrane soreness review across 12 randomized trials found stretching had little or no effect on delayed muscle soreness after exercise. Use stretching for flexibility and range, not as injury insurance.
Where does mobility matter most for runners?
Running needs usable hip and ankle motion, not extreme flexibility. Mobility work targets hip flexors and extensors plus ankle dorsiflexion, which is the shin moving forward over the foot.
Stiff ankles are linked to altered stance mechanics and extra shin and calf stress. Runners with pinching in front of the ankle, early heel lift or knees that cave inward should give ankles and hips priority. Harvard Health points to the same practical split: light jogging plus dynamic mobility before, static holds for the cooldown, stopping with pain and avoiding bouncing.
