Having really struggled with W7R1, I'm pleased to report that W7R2 was way better and I was even able to speed up for the last 2 minutes and finished with the elation I had experienced in earlier runs so that was all good.
However, the next day the back of my knee had really stiffened up and I could feel a tight 'pull' up from through the back of my knee and up the back of my thigh. It really has been very painful. I'm walking with a limp and this dull ache has had me reaching for pain killers. I'm doing some gentle stretches which seems to help a little. I was supposed to do W7R3 today but that's out of the question. I'm hoping another couple of rest days will make all the difference but does anyone know what I can have done and how I can avoid this happening again? Really hoping I haven't scuppered the whole thing.
