The Fat Ass as we lovingly call it began in 2003 with 23 participants who didn't quite know what they had gotten themselves into and who fell in love with running the trails of the Batawa area. Over the years the Fat Ass has grown to be one of the biggest trail races in Ontario, and despite the size of it, we maintain the inclusive atmosphere so everyone feels welcome; fast, slow, young, old, runners and walkers. We have various distances, with various start times:
- 50km- 730am
- Bad Ass 6 Hour- 8am
- 25km- 915am
- 10km- 12pm
- 7.5km- 1pm
- 5.5km- 2pm
- Big Bum Kids' 1km- 130pm
NEW FOR 2024 - 50KM Rules/Regulations
There is a hard cutoff time of 5pm, though we are moving the start time to 730 to give an extra 1/2 hour compared to previous years.
Runners will be required to have a headlamp after 3pm.
Runners not on their last loop by 3:45pm will not be allowed to finish their last loop.
Sorry, no pacers, just bug your friends to sign up with you. :)
The Fat Ass is a mixed bag of tricks. Rocks, roots, wide trails, single tracks, wooden bridges, creek crossings, hills and meadows. Sometimes snow, often mud, sometimes nothing but sun. Its a guaranteed adventure, brace yourself for anything.
There are three aid stations. One on the south loop, one on the north loop and one in between. These are all stocked with water, Tailwind, and a plethora of snacks.
First Aid is provided by Neil Graham of Stat Med Canada
Porta potties will be available at the start/finish line area
There is ample parking at Batawa Ski Hill. There is also overflow parking at the Batawa Community Centre. Please do your best to not park on the streets and if you are required to do so not block the driveways of residents.
Medals will be awarded to the first, second and third place male and female for each distance.
