Made the mistake of checking out what week four entails, and how got myself really panicking about managing it!
Having finished week three today, I was feeling confident, but the three minute jogs seem to kill me - five minutes is asking a lot, especially with the shorter recovery times!
Did anyone else have a problem with this (what seems like a) big step up in requirement?
I'm willing to give it a go, because I won't know until I try it, but I have very little hope right now!
