100x100 Half L'Escala combines a sea swim, road bike, and road run into one race morning on the Costa Brava, in L'Escala, Girona. This Catalonia triathlon event takes place around mid-April, offering three main distances: Sprint, Olympic, and Half Ironman. The Half Ironman totals 113 km, comprising a 1.9 km swim, 90 km bike, and 21.1 km run. The Olympic race covers 51.5 km, with a 1.5 km swim, 40 km bike, and 10 km run. The Sprint is 25.8 km, featuring a 750 m swim, 20 km bike, and 5 km run.
The course winds through seaside, sand, town streets, and natural areas near L'Escala, differing from a closed-course sports park race. The Half Ironman begins first in the early morning, followed by the Olympic and then the Sprint, providing the longer-distance athletes the earliest start. Swimbike M and Swimbike L options are available for those preferring a swim-and-bike format without the run. Elevation gain for the main distances is not provided in published listings; athletes should consult the race website for current route details before selecting a distance.
