2025 Course Details
The course loops around Lost Lake Park and through Whistler Olympic Plaza. The exchange point is at the Start/Finish Line at Whistler Olympic Plaza. While your teammate is running, you can stroll through the Village and pick up a coffee or hang out in the beer garden to cheer them on.
The 50-mile (80-kilometre) relay course consists of 8 loops of 10 kilometres. The 8-person relay has participants run a 10K loop each, while the 4-person relays run 20K legs (two loops). The solo ultra is beginner-friendly, with five, 10k loops of the Whistler Valley Trail, multiple support points, and the security blanket of being within reach of civilization for your first Ultra.
