Last night I was out running my 3rd run of week 1 and had a fair amount of pain in both my calves. I have had this a tiny bit since run 2 but it only seemed to bother me in the mornings, put it down to tight muscles and had a soak in the bath but I went out to start week 2 this morning ( I normally have 1 day between runs but because of a tight schedule I had to skip that this once) and the pain was so bad I wanted to give up. I finished the run and in hind sight that was stupid I should have stopped because I could only just walk by the time I got back. Its been a few hours since then and they are nowhere near as bad just uncomfortable but I am not sure if this is normal or not?? I am 24 and about 1.5 stone over weight . I don't think its my shoes. I used to run for very short amounts of time 3 days a week before Christmas and I never had anything like this?
