An equilateral triathlon is a triathlon in which each leg would take an approximately equal time. These triathlons were proposed by Wainer and De Veaux (1994) to redress the bias in favour of cycling over running and particularly over swimming in standard triathlons. Cycling occupies about 78% of the typical race distances, running 19%, and swimming 3%. Based on world-record times for similar distances, cycling would take 54% of race time, running 31%, and swimming 15%.
A triathlon is a multisport race with three continuous and sequential endurance races. The word is of Greek origin, from τρεῖς or treis (three) and ἆθλος or athlos (competition).
Howard Wainer is an American statistician, past principal research scientist at the Educational Testing Service, adjunct professor of statistics at the Wharton School of the University of Pennsylvania, and author, known for his contributions in the fields of statistics, psychometrics, and statistical graphics.
Cycling, also called biking or bicycling, is the use of bicycles for transport, recreation, exercise or sport. People engaged in cycling are referred to as "cyclists", "bikers", or less commonly, as "bicyclists". Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadracycles, recumbent and similar human-powered vehicles (HPVs).
In Wainer and De Veaux's equilateral triathlons, cycling should take approximately 33% of race time, running 33%, and swimming 33% for a ratio of roughly 1:8:3.5 for distances of swimming / cycling / running. Examples would be:
Name | Time per leg | Swim | Bike | Run |
---|---|---|---|---|
Sprint | 10 minutes | 1 km (0.6 mi) | 8.5 km (5.3 mi) | 3.9 km (2.4 mi) |
Olympic | 28 minutes | 2.7 km (1.7 mi) | 22.4 km (13.9 mi) | 10 km (6.2 mi) |
Ironman | 127 minutes | 12 km (7.5 mi) | 96.2 km (59.8 mi) | 42.2 km (26.2 mi) |
Wainer and De Veaux's proposal appears to have had little influence on triathlon race distances.
In sport, racing is a competition of speed, against an objective criterion, usually a clock or to a specific point. The competitors in a race try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific goal.
A relay race is a racing competition where members of a team take turns completing parts of racecourse or performing a certain action. Relay races take the form of professional races and amateur games. Relay races are common in running, orienteering, swimming, cross-country skiing, biathlon, or ice skating. In the Olympic Games, there are several types of relay races that are part of track and field.
Duathlon is an athletic event that consists of a running leg, followed by a cycling leg and then another running leg in a format similar to triathlons. The International Triathlon Union governs the sport internationally.
The sport of aquathlon consists of a continuous, two-stage race involving swimming followed by running. The International Triathlon Union (ITU) and its member federation organizations sanction competitions and govern the sport. An aquathlon is also called an "aquathon." The ITU and USA Triathlon sanctioning organizations generally use the term aquathlon.

An indoor triathlon is a nonstandard variation of the triathlon and consists of three events: swimming, cycling, and running. The swim is held in an indoor pool, the cycling takes place on stationary bikes, and the run takes place on an indoor track or treadmill. Indoor triathlons are generally held in fitness clubs to accommodate all three sports.

In computing, a Digital Object Identifier or DOI is a persistent identifier or handle used to uniquely identify objects, standardized by the International Organization for Standardization (ISO). An implementation of the Handle System, DOIs are in wide use mainly to identify academic, professional, and government information, such as journal articles, research reports and data sets, and official publications though they also have been used to identify other types of information resources, such as commercial videos.
