About the race

TO50 is a self-supported ultramarathon held in Toronto along the waterfront and city trails. The organisers provide a GPS route and a midway aid station; participants carry their own supplies except for the halfway point.

Distances:

  • 50 km - Self-supported, 12-hour cutoff; CA$50 deposit refunded if finished within cutoff.
  • 80 km / 50 miles - Self-supported, 14-hour cutoff; CA$80 deposit refunded if finished within cutoff.

The course starts on the waterfront and follows the Martin Goodman Trail, Tommy Thompson Park, the Lower Don River Trail, the Eglinton section referred to as the Eglinton grind, and finishes on the Humber River Trail. A GPX file is sent before race day to match the given route. The midway aid station is located at approximately 25 km and supplies water and gels.

Event rules include following the supplied GPS route, obeying all traffic laws, leaving no trace, and looking out for other participants. Headphones are not allowed on roads with traffic. Cash prizes are offered for women and men: 1st CA$300, 2nd CA$200, 3rd CA$100. Entry is limited to 75 participants per distance. Visit the organization's website for the most recent information.
