Since its inaugural race in 2019, the IRONMAN 70.3 Les Sables d'Olonne-Vendée triathlon has featured a canal swim, a bike ride through the forest, and a half-marathon along Les Remblai promenade.
Les Sables d'Olonne, meaning "the sands of Olonne," is a seaside town on the western French coast, known as the Côte de Lumière. The region boasts a variety of landscapes, from beaches and rugged coastlines to pine forests and wetlands.
Transition 1 (T1): Located on the Place du Vendée Globe. Athletes retrieve their blue cycling gear bag after climbing the main pontoon (250m). Facilities include toilets, bike mechanics, water/cups, chip service, and a medical tent.
Transition 2 (T2): Located in the same carpeted area. Athletes drop off bikes and pick up red run gear bags. Facilities include toilets, chip service, penalty tent, and a medical tent.
Relay teams can consist of two or three athletes dividing the swim, bike, and run legs. All team members must be at least 18 years old on race day and must attend onsite registration together. The single team timing chip acts as the baton passed during transitions.
