The Triathlon International Vallée de Joux is a short-distance triathlon featuring a 500m swim in Lake Brenet, a 22km cycle around Lake Joux, and a 4.5km run along the shores of Lake Brenet.
What this race demands
This short-distance triathlon demands high-intensity output across swimming, cycling, and running segments over a modest total distance of 27 km.
Short-Distance Intensity
Because the total distance is only 27 km—including a 500m swim, 22km cycle, and 4.5km run—athletes must sustain a high aerobic and anaerobic effort from start to finish without pacing for a long endurance event.
Multisport Transition Efficiency
The race requires seamless transitions between three distinct disciplines, demanding cardiovascular adaptability as the body moves from horizontal swimming to cycling and finally running.
