The Olympics use the Olympic distance triathlons funnily enough.
Impressive stuff Jon.I completed the London marathon in 3 hours 49 this year, 33 minutes better than last year - better training this year. Going to do it again in 2013 to try and get closer to 3 hours 30, then look for the next challenge. Thinking triathlon but the open water swim puts me off a bit, whats your experience of it?
