I started running in July 04, after accidently getting on a set of scales. Back then I was 15.8. :eek:
After that I got bitten by the bug big time. Now I've got down to 12.3, and plucking up the courage to enter my first 10k soon.
I was 20 when I started, and it was mainly to build fitness for Officer's Training Corps training at the weekends - my first run was 10miles, and started off on two runs a week (one 10-15miler at the weekend, and 1 30min speed session during the week)
