Fat Ass Trail Run
The Fat Ass Trail Run takes place at Batawa Ski Hill in Quinte West, Ontario on November 15, 2026. The event began in 2003 with 23 participants and has grown since then; the organizers describe an inclusive atmosphere welcoming runners and walkers of different paces and ages.

- 50 km
- Bad Ass 6 Hour timed event
- 24.5 km
- 16.5 km
- 10 km

- 5 km
- Big Bum Kids 1 km
The course mixes rocks, roots, wide trails, single track, wooden bridges, creek crossings, hills and meadows. Conditions can vary seasonally with mud, snow or sun; participants are asked to keep headphone volume low so others can pass safely.
There are three aid stations positioned around the course, stocked with water, Tailwind, and various snacks. The event is cupless; participants should bring their own flask, speed cup or hydration bladder. First aid is provided by Stat Med Canada. Porta potties are available at the start/finish area. Parking is available at Batawa Ski Hill with overflow at the Batawa Community Centre.
Specific 50 km rules include a hard cutoff late in the day, a requirement to carry a headlamp for use after the afternoon, allowance of pacers on the final loop, and permission to use poles. The event does not offer refunds; transfers between participants are allowed until October 31. Fat Ass shirts and Bad Ass swag require pre-order by October 25; medals are only awarded to the top three male and female finishers per distance while kids in the 1 km receive participant ribbons.
