About the race
The Fat Ass Trail Run is scheduled for November 15, 2026 at Batawa Ski Hill in Batawa, Quinte West, Ontario. The event began in 2003 with 23 participants and now offers multiple trail distances and a kids 1 km race.
Distances include:
- 50 km
- Bad Ass 6 hour
- 24.5 km
- 16.5 km
- 10 km
- 7.5 km
- 5 km
- Big Bum kids 1 km
The course mixes rocks, roots, wide trails, single track, wooden bridges, creek crossings, hills and meadows. Surface and weather vary and can include snow, mud or sun. Headphone use is discouraged or should be kept quiet to allow others to pass.
There are three aid stations stocked with water, Tailwind and snacks. The event is cupless; participants must bring their own flasks, speed cups or hydration bladders. First aid is provided by Stat Med Canada. Porta potties are available at the start/finish area.
Organizers do not offer refunds. Transfers between individuals are allowed until October 31st and must be arranged at participants own expense. Fat Ass shirts and Bad Ass swag require pre order by October 25th; 6 hour entrants who register after that date will not receive included swag. For the 50 km there is a strict cutoff and a requirement to carry lighting for later in the day; pacers are allowed on the last loop and poles are permitted.
Awards follow a minimalist format: no participant medals, medals to first three men and women per distance, and participant ribbons for the kids run. Visit the organization's website for the most recent information.
