Welcome
Sinister 7 Ultra: July 9-11, 2021
NEW! Our last chance for an ultra this fall. Check out our shorter, colder, and still really challenging S3 Ultra.
Welcome to the Sinister 7 Ultra — a race that may be the greatest challenge of your life. The 100-mile and 50-mile courses will take you through the most rugged, remote and beautiful terrain in Alberta's stunning Rocky Mountains. With 6,400m of elevation gain across the full course, this race will punish those who are not prepared.
The Sinister 7 is open to solo runners or teams of up to seven and racers have 30 hours to complete the grueling event. The course is split into seven stages, each featuring a geographic and historic highlight of the area. The race's name is inspired by the treacherous Seven Sisters Mountain that looms over much of the course.
New! For 2021 we are introducing a 50-mile course option for soloists. Full details will be released in late October. The 50-miler will be limited to 200 runners. We will also be introducing a "mini-triple" for those who do the short distance at each of our three ultras. Keep your eye on the Racer Information Package for upcoming details.
