I pulled my badly on a trampoline, what a bitch!! It didn't effect my training much. I supplemented running with the recumbent bike, iced, and alot muscle rub.
After about 4 wks post injury I started some light stretching, took a very conservative approach because I am a competitive 5k runner and was cautious about it reoccuring. Right about now it feels good.
The true test will be tommorrow. I am racing for the first time in months. I'll let you know. Good luck
