2026 XTERRA Sleeping Giant

XTERRA Sleeping Giant 2026 brings trail running and off-road multisport racing to Thunder Bay on August 16. For runners, the event includes half marathon, 10K and 5K trail run options on rugged terrain near Lake Superior.

The broader XTERRA weekend also includes triathlon, duathlon and relay categories, but the running listing focuses on the trail run options. The race venue is listed at 400 Lyon Boulevard West in Thunder Bay.

For more northern Ontario options, see Ontario trail races and Thunder Bay races.

The trail runs use the XTERRA Sleeping Giant course setting in Thunder Bay, with rugged Boreal Forest terrain near the shore of Lake Superior. The half marathon trail run is a multi-lap race on the challenging run course, while the 10K and 5K give runners shorter ways to take part in the same off-road festival setting.

The record keeps the running options separate from the triathlon and duathlon categories so the public race page stays focused on runner-facing events.
