Well I am 19 stone and 6 pounds, a positive wall of muscle, do 2 miles a week training and can run 10k in 29 minutes and 16 seconds. Can any readers beat that ?
I might add that when I was 22 stone (I have lost a tad off my biceps) I could do 10k in not far shy of 27 minutes.
Just goes to show that light does not always mean quick.
