I have just finished week 4 as of last night. It was quite tough but I did it, so want to keep my momentum going.
I have stuck to the plan like clockwork, running every second day - but I am wondering what is best to do. Tomorrow I am due to run week 5 run 1, but I am unable to due to commitments, so should I run tonight (no rest day), or Friday with an extra rest day.
I know it seems a small question but I don't want to lose any of the foundation I have built, and wondered if extra rest days do that. If I was finding it easy it wouldn't matter but I feel like I am at my limit by the end of the run.
