Race Info
The Treherne Marathon, billed as Run for the Hills, is held on a Sunday in September in Treherne, Manitoba. The marathon and half marathon start in town at 9:00 AM and run country roads through the rolling Tiger Hills, with bison, cows and horses along the route, before finishing under an arch in town. The marathon is an official Boston qualifier sanctioned by the Manitoba Runners' Association, and the weekend also has a 10K, a 5K and a 1 mile.
