Equilateral triathlon

Last updated

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%.

Triathlon sport which combines swimming, cycling and distance running

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).

Cycling riding a bicycle

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:

NameTime per legSwimBikeRun

Ironman127 minutes12 km
(7.5 mi)
96.2 km
(59.8 mi)
42.2 km

Wainer and De Veaux's proposal appears to have had little influence on triathlon race distances.
