A day before my regional meet, last Tuesday, I strained my hamstring pretty bad . I ran thru it and made it to States in both the 400 and the 4x400, which is Saturday. As a precaution, I didn't run Thursday, Friday or Saturday to rest. Today, I went to the track to go jog but it has been raining bad all day and now I'm forced to stay inside and run tomorrow. Will 4 days straight without running affect my fitness level or performance ? Will I still be able to be in peak shape by Saturday ?
