100x100Half Platja d'Aro 2026

100x100Half Platja d'Aro sends triathletes into the Costa Brava water before a long run through transition to an unusual indoor bike zone. The race is based in Platja d'Aro, in Girona province on the Catalan coast, and usually runs in October as a late-season triathlon weekend. Athletes can choose Sprint, Olympic, Half, or Aquabike formats: the Sprint is 750 m of swimming, 22 km on the bike, and 5 km running; the Olympic is 1.5 km, 44 km, and 10 km; the Half stretches to about 1.9 km of swimming, a long road ride, and a half marathon run. The course uses three very different parts of the area. The swim is in the Costa Brava, the bike leg heads onto Girona's roads, and the final run follows a Via Verde rather than ordinary city streets. That mix makes the race attractive to triathletes who want one last hard effort before ending their season, from short-distance racers chasing speed to Half-distance athletes looking for a longer day out. The covered transition area is one of the more practical details: it gives the event a setup that feels different from a standard beachside triathlon.
