This grueling triathlon distance consists of a 2.4-mile swim, a 112-mile ride and a 26.2-mile run. Ironman pros post bike splits as fast as four hours and 15 seconds -- a more than 26 mph average pace, which gets all the press. You may wonder how more average mortals perform on the bike portion of the course so you can gauge your training and potential race-day performance.
Since the shortest swim distance in a triathlon is likely 400â800 meters, and typically more, one needs to consider what training is required to sustain a good pace for the distance to be swum. 800 meters is no sprint.
