not to be a [wagon], and i don't mean to discourage you at all, but consider running some slow runs (with a good pair of shoes) while waiting for the fracture to heal (not sure if its a stress fracture from running or not). but if you can't run at 70% of your sprint speed (ex- 15.5 second 100) then you need to take some time off as fractures are pretty serious injuries. i'm not sure if it IS healed or if it is in the process of healing, but here are some things that are helpful: ABC: stand on one leg, slightly bend that knee. stick your other leg out and draw the alphabet. 1-2 sets on each leg runners pose: bend your knee slightly more than in the last exercise. with the other leg bend your knee at a 90 degree angle behind you, and swing your arms as if running. 30 seconds. stair hangs stand sideways on a stair. hang one foot/leg off sligthly. keep both legs straight and lift your free leg up and down. your knees should not bend. its all in your hips I came off crutches in December.
