I did the first workout of Week 5 last night, which consists of three intervals of run 5 minutes/walk 3 minutes. The last run was a challenge, but no huge deal.
The bigger issue right now seems to be my right leg. I'm not loving how my right shoe fits or my form on that side is screwy or something. I've started getting a shin splint on that side and the inside of my right knee is getting more sore with each workout. I'm not sure how to address this - head to the running store for analysis???
I did some of my walking at 4.0 and ran at 4.8.
