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. It is widely considered one of the most difficult one-day sporting events in the world.
What does it take to complete an Ironman®
Most Ironman events have a strict time limit of 17 hours to complete the race. The race typically starts at 7:00 a.m.; the mandatory swim cut off for the 2.4-mile (3.9 km) swim is 9:20 a.m. (2 hours 20 minutes), the mandatory bike cut off time is 5:30 p.m. (8 hours 10 minutes), and the mandatory marathon cut off is midnight (6 hours 30 minutes). Any participant who manages to complete the triathlon within these timings becomes an Ironman®.
The History of the Ironman® Triathlon
The name “Ironman Triathlon” is also associated with the original Ironman triathlon which is now the Ironman World Championship. Held in Kailua-Kona, the world championship has been held annually in Hawaii since 1978 (with an additional race in 1982) and is preceded by a series of qualifying Ironman events. The Ironman World Championships have become known for their grueling length, harsh race conditions, and Emmy Award-winning television coverage.
Extreme Endurance Races
Other extreme endurance races exist that are of the same distance as an Ironman triathlon but are not produced, owned, or licensed by the World Triathlon Corporation. Such races include The Challenge Family series’ Challenge Roth or the Norseman Triathlon.
What Does Doing an Ironman® Triathlon Involve
Completing an Ironman® distance triathlon is much more than just swimming 2.4 miles, cycling 112 miles, and running a full marathon or 26.2 miles.
