The race of the lakes: a 55-kilometer point-to-point from Salardú to Vielha traversing the Colomèrs glacial lake cirque — the largest in the Pyrenees — with 3,300 meters of ascent and 3,700 meters of descent. The PDA combines spectacular high-altitude scenery with a significant technical descent to the finish in Vielha. Known for selling out quickly each year, it is also an OCC®-equivalent UTMB World Series race offering direct Finals entry for top finishers. No crew assistance is permitted at any checkpoint.
