Course Description

Course Description

Runners will begin their day in Creekside Plaza, starting a short ascent up Whistler Mountain before making their way over to Whistler Village. After leaving the first Aid Station at Uphill Prep, runners will make their first significant ascent up Blackcomb Mountain, summiting at the second Aid Station, Rendezvous. 70k runners will get to experience one of the most scenic trails on Blackcomb Mountain, heading out on a out and back loop along the Lakeside Loop and Overland Trail. After returning to Rendezvous for a second time, runners will make the long descent down to Uphill Prep - 2.

Leaving Uphill Prep - 2, runners will start their journey to the summit of Whistler Mountain via the historic Singing Pass Trail. Runners leaving the Fitzsimmons Hydration Station are required to top off their water, electrolytes and nutrition before continuing to the summit of Whistler via Singing Pass with some of the most scenic sections of the course. After the long ascent, runners will find themselves at the Piccolo Summit Hydration Station to resupply before making their final ascent to Whistler Summit.

Finally at the Whistler Summit Aid Station, runners are greeted with some of the most breathtaking panoramic views and have reached the highest point on the course at 7,100'. After stocking up on supplies, runners will start to make their descent off Whistler Mountain to the Middle of Nowhere Aid Station before making a 4.3 mile loop back to the same location and final Aid Station on the course. Leaving Middle of Nowhere - 2, runners will make their final descent to Creekside Plaza for a much deserved finish, celebration and rest!

Kilometer-Effort (km-effort)

Kilometer-Effort (km-effort)

The 4 race categories are based on the km-effort, a globally recognized formula for measuring the race distance in trail running by considering both the distance and elevation gain to calculate the perceived distance.

The km-effort is calculated by adding 1km to the race distance for every 100 meters of elevation gain.

For example, a race of 50km and 2,500 meters of elevation gain has 75 km-effort.
