Altriman is a long-distance triathlon held in Les Angles, in the Pyrénées-Orientales of southern France. The listed race distance is 241.8 km, and it takes place in July. Altriman is considered one of the most challenging European triathlons, with its name reflecting a focus on mountain racing rather than a flat, fast Ironman-style event.
The race attracts dedicated triathletes prepared for a demanding Pyrenean course and a lengthy day covering the swim, bike, and run segments. Erik Merino, a professional triathlete from Muntanyola, is notably associated with its recent history, having won the Half Altriman three times.
