Lost Lake Park · Whistler, BC
Lost Lake is one of Whistler's hidden gems — a pristine mountain lake nestled in old-growth forest just minutes from the village. Crystal clear water, a sandy beach start, and the electric energy of a mass start. This is where it begins.
The Championship course is a single 1500m loop; the Sprint a 750m loop. Wetsuits are permitted and recommended. Swim caps are provided with your race kit.
At this time of year we expect the water to be reasonably cold ~14°C (57.2°F) – 18°C (64.4°F). Air temperatures may also be cool in the morning.
Swim rulings will be made 1 hour before the swim starts. We have never not held our full distance swim. While we cannot guarantee anything, expect to swim the full distance of your race, and expect wetsuits to be mandatory.
* Cut-off times: 30 mins for Sprint (750m) · 60 mins for Championship (1500m)
Whistler's Zappa trail network is the crown jewel of the course. Fast, flowing, technical in places, and absolutely beautiful. This is what MTB triathlon is all about: actual trails, actual roots, actual smiles.
The Championship course does two laps; the Sprint does one. The trails are rated green to blue — accessible to confident beginner and intermediate riders, genuinely engaging for experienced ones.
Even though Whistler X Tri is run on Whistler's easiest mountain bike trails, it is still a challenging course for some. That being said, we have had athletes in their 60's and 70's complete the course.
We highly recommend athletes pre-ride the course if possible. Even though the course will be well marked, it is your responsibility to know the course. We will be offering pre-race clinics — sign up to our newsletter to stay in the loop.
The run leg winds through old-growth forest, across slatted wooden boardwalks, and for those doing the Championship, to the views over Green Lake. The smell of the forest, the light through the trees, and the knowledge that the finish line is getting closer — this is the stretch where people start to grin.
The Championship run is approximately 10km with around 140m of elevation. The Sprint is approximately 5km. The final stretch brings you back through the event village to the welcomed finish line.
