Ultra Obscura : Mont Sutton
Ultra Obscura is an event organized by Sinister Sports, taking place at Mont Sutton in Sutton, Quebec, on June 13, 2026. The event is limited to 200 places and is held entirely on trails with no asphalt sections. The organizers emphasize trail sustainability.
Available distances are:
- 84 km
- 66 km
- 52 km
- 42 km
- 24 km
- 10 km
The format differs from a classic ultra trail. The race emphasizes strategy, planning and decision making as much as endurance. Participants should expect technical, uneven trails that require strong concentration and views of the Sutton mountains. There is a relay option for the 84 km distance and a children's race called La Salamandre.
Included items are a technical t-shirt, a pre race meal, race photos, a personalized medal, live timing updates and medical support provided by first responders and professional paramedics. Part of the registration fees supports PENS and Plein Air Sutton for trail maintenance. Prize presentations are scheduled after loop completion; awards for the 66 km and 84 km races take place Sunday morning. Visit the organization's website for the most recent information.
