I've never done a triathlon before, but regularly run marathons and have been commuting by bike for 6+ months now. I'm in good shape and feel I could handle the running and biking portion of a half Ironman. I would really like to try, but swimming practice is a problem for me. My current gym (paid up until Feb 08) does not have a pool, and the chances of finding a pool are low. I live in Japan where they forbid tattoos in the pools. I could possibly cover it with a shirt, but not likely. Considering I'm in good health, have enough endurance, do you think it's possible to make it through 1.2 mile swim with no practice?
