FT, my thought's too, I agree with Simon. However there is another possibility with your sports:
whitewater and slalom kayaking, running and downhill/cross country mountain biking,
These all suggest a personal fitness regime which is good, but if you became a team organiser, ie in management for athletics or organisation of the events.
For instance one of my cpls won the 'Sportsman of the Year' award for coarse fishing. Not only because he won a number of cups, which he did, but because in the space of two years from starting the sport he became the east of England area secretary too.
Maggot strangling was indeed a solitary sport but he rose above that and showed initiative, team work and leadership.
