I just couldn't do it! I just about managed 20 minutes, and then my body just refused to go on, even though I was very slow (had to slow down twice). For some reason, I found W6R3 a much bigger challenge than W5R3. I feel very disheartened, as I was really looking forward to this, but the whole week was a struggle.
Should I repeat this run? Repeat the week? Or go to W7, seeing as it's the same run 3 times? Help!
