4 triathlon events in Milton, Ontario

Online registration is closed for Milton. We will still be taking registrations on site, starting at 7:30am on Sunday!

The first event of the Subaru Triathlon Series and one of the first outdoor Triathlons in Ontario to kick off the season! The event is based out of Kelso Conservation Area, with the swim and run routes all within the park and the bike on local roads. Please note that due to road construction and changes in the area, that there will be some adjustments to the bike and run courses. The sprint courses will be: 750m Swim, 28km Bike and 5km Run.

Unfortunately, due to timing and logistical issues due to changes in the area, the Try-A-Tri will not be taking place this year.

Due to construction at the Milton Sports Centre, TRi KiDS Milton will now take place on July 5. The race will return to Labour Day weekend in the 2027 season.
