About the race
Sinister 7 Ultra is Western Canada’s biggest trail race, held in Blairmore, Alberta. The event offers four distances in 2026: Solo 100-mile, Solo 50-mile, Solo 50k, and Half Marathon, plus a Sinister 7 Relay for teams of up to seven. Racers have 30 hours to complete the course, which is split into seven stages, each highlighting a geographic or historic feature of the area.
The race’s name nods to the Seven Sisters Mountain that looms over much of the route. Open to solo runners or teams, with race information packages available on the official site. Visit the organization's website for the most recent information.
