IRONMAN San Juan
IRONMAN San Juan on 1 November 2026 is a full-distance race in western Argentina under the Andes: 3.8 km swim, 180 km bike and 42.2 km run, with World Championship qualifying slots on offer.
San Juan is a wine province in a high desert, and that sets the character of the day. The air is very dry, there is no humidity to slow evaporation, and it is easy to fall a long way behind on fluid without ever feeling like you are sweating hard. Weigh yourself in training and know your rate before you get here.
The bike is rolling rather than flat, on wide roads with long exposed sections. Afternoon wind coming off the mountains is a normal feature rather than bad luck.
November is spring here and the field is small next to the European races. A small full-distance field means a lonely bike leg, and if you are chasing a slot, a thinner age group to get through.
