TO50 : 50 km self-supported run in Toronto
TO50 is a self-supported 50 km ultramarathon through Toronto held on September 5, 2026. Entry requires a $50 deposit that is fully refunded to anyone who completes the 50 km within 12 hours. The first edition is limited to 50 participants and finishers receive a piece of memorabilia.
The route starts near Lake Ontario and follows city trails and streets, including the Martin Goodman Trail, the Lower Don River Trail, a roughly 10 km section on Eglinton, and the Humber River Trail. A halfway aid station at about 25 km provides water and gels. Organizers send a GPX file before the event for navigation.
The format is self-supported except for the mid-race aid station. There is no official permitting body or formal timing; the event operates without sponsors. Rules require following the GPS route, obeying traffic laws, leaving no trace, and looking out for other participants. Medical crews on bikes patrol the course. A cash-prize podium awards the top three finishers. Visit the organization's website for the most recent information.
