Sol I had some tightness in my calf. I really thought that I had hurt myself bad – like a micro tear or something. Not career ending but career halting. In years past I would have tried to run on it the next day and dug myself into a deeper hole. I preach 3 days off will save you 3 weeks; 3 weeks will save you 3 months. But in reality I have pushed through the pain. Not smart.
