6th Triathlon of Agon Coutainville

The 6ème Triathlon d'Agon Coutainville takes place on 21 June 2026 in Agon‑Coutainville, Normandy, and is co‑organised by Enduro des sables d'Agon Coutainville and the Coutances Triathlon club. The event offers two main formats — XS and S — accommodating both individual athletes and relay teams, and is staged along the town's seafront promenade with sea swimming as part of the course. Entries are open and managed via the official registration partner; capacity is limited per format so early registration is recommended.

The courses feature sea swimming, a bike leg run on closed circuits to traffic and a short run along the promenade, with the XS (400 m swim / 10 km bike / 2.5 km run) and the S (750 m swim / 20 km bike / 5 km run) distances. Relay places are available for each format with a capped number of team slots. For full race rules, the detailed agenda, parking and parcours maps consult the organiser's site and the dedicated pages linked from the official homepage.
