I just finished w6r2. It was better than I thought it would be!
Since about halfway through week 4, I've been experiencing some tightness in the back of my leg behind my knee right after I ran, but since week 5 I've been getting it during my runs...I'm not sure what I'm doing wrong.. I'm going slow, I'm stretching, I'm hydrating, I'm eating etc I think I'm doing everything right (within my ability) yet this keeps happening. It goes away after some rest. It feels like the beginning of a cramp but doesn't quite go into one if that makes sense.
However, today as I was in the second 10-minute stint of the run it started again so instead of slowing down more I went a little harder and faster (nothing amazing now) for about 10 seconds, and that eliminated it completely!! Does anyone know why that is or has anyone else experienced this?
