IRONMAN 70.3 World Championship 2026

The IRONMAN 70.3 World Championship is the top event for athletes competing in the half-Ironman distance: a swim, a long bike course, and a run totaling 70.3 miles. It is part of the larger IRONMAN series, where athletes qualify through races worldwide, unlike a typical local road race entry. Nice, France, defines the course: the swim takes place in the Mediterranean Sea, the bike route ascends and descends through the Alpes-Maritimes region, and the run follows the Promenade des Anglais. This course demands more than consistent pacing, as the bike leg includes significant elevation changes before athletes reach the flat, open coastline for the final miles.
