Registration for 2025 is open!

We have made some slight schedule changes from previous years aiming to spread out the races and avoid the back-to-back race weekends (Niagara and Owen Sound in 2024).

MILTON – June 1, 2025 – Due to major construction in the area, we are still working on finalizing a suitable route for 2025. We are hoping this will be completed in the next few weeks, but have decided to hold off on opening registration for Milton for now.

GUELPH LAKE 1 – June 14/15, 2025 – Host of the Triathlon Ontario Club Championships! The Sprint Triathlon and Duathlon will have qualifying spots for the 2026 World Championships*.

OWEN SOUND – July 20, 2025 – The Standard (Olympic) Triathlon and Duathlon will have qualifying spots for the 2026 World Championships*.

NIAGARA – August 9, 2025 – New date and race now on Saturday!

GUELPH LAKE 2 – August 30, 2025

*The 2026 Triathlon championships will be taking place in Pontevedra, Spain and the Duathlon championships will be in Abu Dhabi.

Our goal as an event producer is to provide an amazing and safe race experience for the best value to our athletes. We know triathlon is expensive, and we are proud to continue to offer the best pricing in Ontario to allow more people access to our great sport. The pricing listed on Race Roster already includes processing fees, but does not include HST or the Triathlon Ontario Fee.

For those looking to take advantage of the Multi-Race discount, this is done online! Click Here to access the Series registration page. Due to the delay in opening Milton, we have adjusted the discount. Register for 3 events will receive a 10% discount and all 4-5 races will receive a 15% discount. All events MUST be registered for at the same time to receive the discount. For those that wanted to use Milton towards the multi-race discount, we would suggest waiting until we open, as the first price increase isn’t until March 1 and we cannot give discounts retroactively.

Unfortunately, we will no longer be taking individual or multi-race registrations by mail, email or phone.

For any other inquiries, please email us at: info@trisportcanada.com

We are excited to to see everyone again in June. Until then, happy and safe training!
