No sponsors. No permission. Just you and the distance.
October 2026.
No sponsors. No crowds. No bullshit. TO50 is a self-supported 50km ultramarathon through the streets of Toronto. You carry what you need. You figure it out. We give you a route, a start time, and water at the halfway mark. The rest is on you.
This isn't a race fee. It's a commitment deposit. Finish the 50km within 12 hours and you get every dollar back. Don't finish? That's the cost of quitting.
No fluff. No hidden fees. That's the deal.
We start at Sunnyside Park, right on the water. If you're lucky, you'll catch the sunrise. The Martin Goodman Trail opens the race — flat, fast, the lake on your right. Enjoy it. It won't last.
The Lower Don River Trail is where it gets quiet. Green canopy, birds singing, the river beside you. You're cruising and you feel good. Don't get comfortable. The tax to leave the valley is the Serena Gundy hill — it'll wake your legs up, and you're not even halfway.
Then comes the Eglinton grind. 10 kilometres of pure Toronto streets. Friends laughing on patios. Families heading to brunch. They have no idea what you're going through. Keep your head down and keep moving.
After that, the Humber River Trail. You'll love it and hate it. It's green, the water flows effortlessly beside you — but by now, the pain is real. Your legs know. Your body knows.
You're almost there. Keep going.
You carry what you need. You follow the route. You finish within 12 hours. Or you don't.
Your first ultra doesn't need to be perfect. It just needs to happen. You have 12 hours. You can walk the whole thing. This is your chance.
You pay $50 to register. Finish the 50km within 12 hours and you get the full amount back. Don't finish? The deposit funds next year's race. It's not a fee — it's skin in the game.
It's grassroots. No permits, no governing body, no official timing. Just a planned route, a start time, and a community of people doing something hard together. You participate at your own risk.
Yes. Walk, jog, run, crawl. You have 12 hours. That's about 14:30/km. Most people can walk that pace. You don't need to be fast. You just need to keep moving.
Water and gels at the halfway point (~25km). That's it. Plan your nutrition, know where public water fountains are, and carry what you need. This is self-supported by design.
Yes. We'll have medics on bikes patrolling the route throughout the race. If something goes wrong, they'll find you. Your safety matters more than any finish time.
GPX file sent before race day. Load it on your phone or watch. The route follows public sidewalks, trails, and paths — no trail shoes required.
This is year one. We want it small, tight, and right. 50 runners who actually want to be there. If it works, we grow it.
