Did the final run of week 1 today but on the very last 60 second run I could only do about 58 seconds and then had to walk for the last two seconds. I did run 2 just fine two days before. A question for all of you who have already 'been there, done that'. Should I repeat week 1 because of this or just carry on to week 2 in a few days time? Don't want to push myself too hard – but maybe it was just a bad day? Having only done three days so far it's kinda hard to make a judgement on this. Thanks for your help.
