The Fat Ass Trail Run began in 2003 with 23 participants who fell in love with running the trails of the Batawa area. Over the years, it has grown into one of Ontario's largest trail races, maintaining an inclusive atmosphere welcoming runners and walkers of all ages and abilities.
The event features a variety of trail distances and a unique timed 6-hour race, attracting over 500 runners annually to enjoy the diverse and challenging terrain in late fall.
