I'm 56, short(ish) and overweight. I go to the gym occasionally but not enough for it to do any real good. I'm fed up with feeling unfit (as a youth I played loads of football and was a 400m runner). My daughter pointed me towards C25K and it seems an ideal way to get myself moving again, and easier than organising a trip to the gym. I've entered the British Heart Foundation Tower of London run next May, and am determined to run the whole thing, and ideally do 10k rather than 5. Tonight's the first night on the programme. Wish me luck!
