Sinister 7 Ultra may be the greatest challenge of your life. The 100-mile (161km) course will take you through the most rugged, remote and beautiful terrain in Alberta’s stunning Rocky Mountains. With over 6,300m of elevation gain across the course, this race will punish those who are not prepared. We also have a 50-mile and 50k option.

The Sinister 7 is open to solo runners or teams of up to seven and racers have 30 hours to complete the gruelling 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.
