Triathlon

The Stonetown Triathlon - happening Summer 2025! On Sunday, July 6, young athletes aged 8-19 years will swim in the quarry, cycle our streets, and run along the Thames River.

The Stonetown Triathlon, organized by the Balance Point Triathlon Club, offers thrilling races for youth aged 8-19. In addition to competitive drafting races for older athletes, it includes recreational and non-drafting events for younger participants.

A triathlon combines swimming, biking, and running into one continuous event, with distances tailored to age groups. Athletes wear timing chips to track their race, and results are posted online. Spectators are encouraged to cheer from the sidelines.

Frequently asked questions

Why was St. Marys selected to host the triathlon?

Organizers approached the Town after participating in the Ontario Summer Games in August 2024:

It could make more people aware of St. Marys and the quarry
It could increase tourism, bringing more money to local businesses
It promotes an active lifestyle and could inspire more people to play sports
It could bring the community together in a positive way
It gives us a chance to show our community pride

With these opportunities in mind, staff made the decision to move forward with the event.

How was the route chosen?

The route was developed around the quarry since the swimming portion of the triathlon comes first.

The cycling route came next. There are specific requirements for the cycling route because of the racing bicycles used by the athletes. The surface of the route must:

Be made of high-quality asphalt with no topcoat treatments
Have no railway crossings
Have no restrictions with respect to grade elevation changes
Have no parked cars

Will residents be able to watch the events?

Yes! Residents with properties on Thomas St., Park St. and Water St. S will have front row seats to the action. We encourage people to cheer on the athletes on as they cycle past.
