Ironman Triathlon. An Ironman Triathlon is one of a series of long-distance triathlon races organized by the World Triathlon Corporation (WTC) consisting of a 2.4-mile (3.86 km) swim, a 112-mile (180.25 km) bicycle ride and a marathon 26.2-mile (42.2 km) run, raced in that order and without a break.
The bike portion of an Ironman race is 112 miles and can take between five and eight hours. A 155-pound person burns 446 calories per hour going 16 to 19 mph. This means you're out on the bike for 6 1/2 to 7 hours, and burn close to 4,500 calories. Go faster than 20 mph and burn 614 calories per hour.
