I just finished run 3 of week 5! I was so nervous that I put it off until the evening instead of the morning - but it was fine! I was actually pretty sad to stop!
Anyway, I've mainly just lurked here for a while and not said anything, but I had to find somewhere to crow about getting past that hurdle. And to ask - is it a bad idea to keep running after the end of your allotted time? I always end feeling I'd like to do more, but I worry about overdoing it by accident...
