The 2023 XTERRA Whistler takes place in and around Lost Lake featuring some of the most scenic trails in the area.

For 2023 we are now a Fall race. Weather conditions may be variable, but it’s usually a stunning time of year in Whistler. Plan to race in any type of weather, in temperatures ranging from 8C to 21C and rain to sun!

Check out our courses with links to high res maps below




The swim will take place in Lost Lake; at this time of year we expect the water to be reasonably cold (~15-18C). However, air temperatures may be cool in the morning. ITU has a specific formula for air and water temperatures.

While we cannot guarantee anything, expect to swim the full distance of your race. But also expect wetsuits to be mandatory.

The Sprint distance will be a single 750m loop and the Championship distance will a 1500m swim, consisting of two loops of the Sprint course, with a beach exit after the first loop.

Each distance will be a mass start as the Sprint race is on Saturday and the Championship distance on Sunday. 

The start area beach is large and the swim course will provide lots of room for racers to spread out. Swimmers with less experience or anxiety may self-seed to the rear of each wave. (Click map to download a bigger map)
