Equilateral triathlon

An equilateral triathlon is a
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%.
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. Isoman Triathlon is a triathlon race with distances roughly equal to the stated portion.
