An ultra-triathlon is a long-distance triathlon. The term generally refers to all triathlon events of distance greater than the Ironman Triathlon. Thus, every ultra triathlon event must involve more than 2.4 miles (3.86 km) of swimming, 112 miles (180.25 km) of cycling, and a full marathon (26.2 mi or 42.2 km) of running. The most common distances are the double, triple, quadruple, quintuple and deca Ironman. Unlike a standard triathlon event, an ultra-triathlon event may not necessarily involve the three component disciplines of triathlon (swimming, cycling and running) in direct consecutive order, but may instead consists of multiple consecutive individual triathlons performed on consecutive days. In October 2015 a quintuple ironman world record will be attempted at the IUTA World Cup Race in Leon, Mexico by ex pro cyclist and multi long-course triathlete Stephen Pearce of Southampton, England. A finisher of 25 ironman races, 2 doubles a triple and a quintuple.
