Four distances, 1,000 swimmers, 170 kayakers, and one magnificent lake. The two day event will host three distances: 1km, 3km, 5km and the crown jewel of the weekend, the 12km crossing of Lac Tremblant. It is challenging and exhilarating – it is you and mother nature at the edge of almost impossible… all rolled into one. It’s an epic adventure. It’s the swim of a lifetime. It’s the Traversée du Lac Tremblant / Canada UltraSwim.
