Your calf muscles work hard when you're running, so they'll need a good stretch when you're done. Here's what to do:
1. Place both hands on a wall with arms extended.
2. Lean against wall with one leg bent forward and the other leg extended back with knee straight and foot facing forward.
3. Keep the heel of your rear foot on that floor.
4. Feel the stretch in the calf of that leg, and hold 15 to 30 seconds. Repeat with the opposite leg.
