I don't know what went wrong at week 6 but ever since W6R1 I have been really struggling with the program. Up until then it was very manageable but lately each run has been hard for some reason.
Yesterday I completed W7R1 and in the first 5 minutes I knew this was not going to be an easy run, my calves burned and my legs in general felt like lead. I finished but it was a struggle all the way and I was jogging very slow, my feet were even dragging so it was more like a shuffle.
It's odd because I had absolutely no problems with W5R3 - the 20 min run, but now I struggle even getting to 20 minutes without feeling like I'm going to die. I think I'm going to start leaving two rest days between every run instead of one and see how that goes.
Well hopefully W7R2 goes better.
