A two-mountain, 24-hour odyssey through BC's alpine crown jewel
Other trail races within 96 miles
The flagship 100K takes runners on a grand tour of both Whistler and Blackcomb mountains. Starting at Creekside Gondola before dawn, the course climbs through Whistler Summit and Roundhouse before descending to the valley base, then ascends Blackcomb past Rendezvous Aid Station, and winds through the surrounding Coast Mountain forest for a triumphant finish at Spruce Grove Park. With nearly 5,900 meters of gain and a 24-hour time limit, night running is virtually inevitable for most of the field. Drop bags are permitted at three mid-course aid stations, and crew can meet runners at three designated locations.
