100x100Half L'Estartit 2026

The 100x100Half L'Estartit begins with an open-water swim near the Medes Islands, off L'Estartit on Spain's Costa Brava. Typically in October, this triathlon is part of the 100x100Half circuit, offering Sprint, S, and M distance options. The Sprint features a 750 m swim, and the longer distances provide a late-season competition without the severe mountain challenges of some Catalan courses. Following the sea swim, participants cycle a closed-road route through a Natural Park and the Baix Empordà, on a circuit noted for its speed. The run takes place near the town, along L'Estartit's seafront promenade with views of the Costa Brava. The event attracts both elite competitors and amateurs, serving as a final race for many triathletes. Organizers and participants highlight efficient logistics and race standards, with the swim often recognized as one of Europe's most scenic.
