The Story

There's something about triathlon in Windsor that doesn't translate to photos. The 750m swim sends you into cool freshwater lake at 16°C — cool enough to want a wetsuit, warm enough to swim without panic. The 20km bike is flat, built for speed and aero position. A 5km flat run finishes what the bike started. The city delivers: Detroit skyline across the water, automotive-city grit, an international border you can swim to but shouldn't. Thirty minutes of controlled chaos — the sprint distance at its finest.

"You don't come to Windsor for a fast time. You come for the experience — and then you surprise yourself."

What It Feels Like

A sprint-distance course in Windsor that suits beginners and those chasing personal bests. The course doesn't fight you — it lets you race. The city's cross-border energy on the Detroit River extends to the race itself — a Windsor pizza and a cold Molson.

🏊 The Swim

A 750m freshwater lake swim at 16°C. No salt sting, no currents, just you and the distance. Lake swims reward smooth technique over brute force.

🚴 The Bike

20km of flat road — a time-trialist's playground. The absence of climbing means aerodynamic position and sustained power determine your bike split. Wind, not gradient, is the variable here.

🏃 The Run

5km on flat Windsor streets. The course is honest — no hills to blame, no descents to coast. What you have left is what you run. In mild conditions averaging 17°C, heat management becomes pacing strategy.
