Hi guys. I'm after a bit of advice. Ive done week one twice now and I'm unsure what to do next. I am overweight, a lot overweight, about 21 stone. I can complete the runs in week one with a bit of s struggle. I think that week 2 is going to be a bit too much for me. Would it be best for me to carry on doing the first week until I get a bit fitter (lighter) or struggle at week 2. ??
