Thousand Islands Triathlon & Runs
About the Event
Race and explore beautiful Brockville!
Run through a piece of Canadian history - the oldest railway tunnel as part of your 1000 Islands run course. We can't overstate it - it's 500 meters long with music, lights, and shade, and it is the best course feature we've ever seen!

This event will sell out early, so sign up before it's too late. The site can only accommodate so many bikes and swimmers but we'll have plenty of room in our run-only events.
Participants love:
- The tunnel. Have we mentioned how amazing it is as a run venue?
- The short transition distances. It's our shortest transition of the year, giving you a chance for a really fast finish time.
