GrassRoots Backyard Ultra 2026 brings Backyard racing back to the Sheep River corridor in Okotoks, Alberta. The event uses a 6.71 km loop format, with runners setting off every hour on the hour until one remains.
The course is built for pacing and patience rather than pure speed. It combines a mostly paved pathway with a short single-track dirt section, plus modest climbing, so the effort stays honest over repeated laps.
For runners who like strategy as much as stamina, this one leans into the Backyard Ultra format from the first loop to the last.
For runners comparing local trail options, it fits alongside other trail races in Okotoks.
