cross country running (school) - top 20 national from about 15 to 18
badminton (school) - rarely finished outside of top 10 national from 14-18, with 2 scottish schools wins at 15 and 16 which i'll never forget
DH MTB (17-24) - was generally somewhere around the middle of the field, although often at the bottom after stacking all the way down
football (15-18) - goal keeper for a couple of reasonable local teams. I was always 2nd keeper and I was always rubbish. never liked football, but all my mates played so enjoyed the company
karate - 11 - 17. I actually had pretty decent results early on, but then it all went pear shaped for some reason!
hmmmm, looking at this tells me a lot about what I focused on after I left school I also note a distinct lack of team sports!
EDIT: doh, forgot about snowboarding. Compete occasionally across all a number of areas from 16 to date. Never placed very highly
