The Relentless Trail Race Weekend

The event is a trail running weekend hosted at The Ark in Denholm, Quebec by Mad Trapper Racing. It offers a range of courses on technically challenging terrain that includes single track, gravel roads, and sections of the Trans Canada Trail.

Distances available span from a short 3K to an ultra 50 miles. Several longer distances have official recognition:

  • 3K
  • 5K
  • 10K
  • 21K
  • 30K
  • 50K
  • 50 miles

The 21K, 30K, 50K, and 50-mile distances are recognized by both ITRA and the UTMB Index.

Course features noted for the event include twisty single-track with roots and rocks, sustained elevation changes, and a private lake view near the highest point followed by mostly downhill running. The location highlights peak fall colors in the Gatineau Hills. The event lists no cutoff times for the courses.

Entries include on-site provisions such as meals, nutrition, hot beverages, aid stations, a finisher medal, free parking and companion admission, a campfire hangout, free beer, prize giveaways, a pre-race orientation, and an awards ceremony. A post-race barbecue is part of the event offerings. Visit the organization's website for the most recent information.
