Grassroots Backyard Ultra

The Grassroots Backyard Ultra is an endurance running event held in Okotoks, Alberta, just south of Calgary. The race features a 6.71 km loop course primarily on asphalt pathways along the Sheep River, with a small section of single-track dirt trail and minimal elevation gain, making it flat and fast. Participants run one loop every hour, aiming to be the last person standing by completing the most loops.

The event also offers timed challenges, including 15-hour (100 km) and 24-hour (100 miles) options on the same course. The open course atmosphere encourages runners to push personal limits in a scenic, community-friendly setting near local amenities and the Rockies.
