Hi all. I'm a very overweight (+ 5stone) beginner on week 2 and astounded that I'm managing to keep on track! Feeling really pleased that so far I'm managing to follow it without passing out. Only problem is the pain in my calf's which is worse when I do the walking bit. By the end of my run they feel not too bad but just wondering if there's anything I can do about it or will it pass the fitter I get? All advice gratefully received.
