About TO50 - Run 50km Across Toronto. Finish and It's Free.

No sponsors. No permission. Just you and the distance.

TO50 is a self-supported 50km ultramarathon through the streets of Toronto. You carry what you need. We give you a route, a start time, and nutrition at the halfway mark. The rest is on you.

The Deal: Pay $50 to commit. Finish the 50km within 12 hours and you get every dollar back. Don't finish? That's the cost of quitting.

The Route: Starting on the waterfront, the course takes you along the Martin Goodman Trail, up the Lower Don River Trail, through the Eglinton grind, and finishes on the Humber River Trail. 50km through your city.

The Rules:

• Self-supported except at the halfway aid station (~25km)

• Follow the GPS route (GPX file sent before race day)

• Obey all traffic laws

• 12-hour cutoff — start 6 AM, finish by 6 PM

• Leave no trace

• Look out for each other

• No headphones on roads with traffic

Cash Prizes: 1st $300 · 2nd $200 · 3rd $100
