The Race
Whistler X Tri (formerly known as XTERRA Whistler) is an off-road triathlon held in the heart of Whistler, BC. A pristine lake swim in Lost Lake, globally renowned MTB singletrack, and trail running through fall's spectacular colours — all in a mountain resort town that has something for the whole family.
This is not your average triathlon. The trails are real, the climbs are honest, and the finish line feeling is something you'll be chasing for years.
