IRONMAN Les Sables d'Olonne
The half at Les Sables d'Olonne has been running since 2019 and uses a different route from the full-distance race held in the same town four days earlier. Check which one you entered before you plan your season around it.
The 1,900 m swim is in the canal, sheltered and straight, which makes it a good course for anyone whose open-water confidence is fragile. The 90 km bike heads into the forest behind the coast, and the 21.1 km run finishes along the Remblai, the seafront promenade, with the beach on one side and cafes on the other.
It is a fast course and a busy one. The Vendée coast in early July is holiday season, so accommodation within walking distance of transition is expensive and gone early, and the roads into town are slow on race weekend.
Atlantic wind, rather than heat, is the usual complication on the bike.
