IRONMAN Versailles
IRONMAN 70.3 Versailles on 11 October 2026 races in and around the grounds of the château: 1.9 km swim, 90 km bike, and a 21.1 km run past the gardens, the canal and the ponds.
The venue is the reason to enter and also the reason this race is unusually strict about where you can be. It is a working heritage site, so course access, spectator points and bike storage are controlled more tightly than at a beach race. Read the athlete guide properly instead of assuming.
Mid-October near Paris means cold water and cool air. The swim is inland still water, the morning is more likely than not to be in single figures, and gloves on the bike are a reasonable choice rather than an overreaction.
Versailles is half an hour from central Paris on the RER, which makes this one of the easiest races in Europe to reach and one of the harder ones to find a quiet, affordable bed near.
