Sinister 7 Ultra

Ultramarathon in Canada's Rocky Mountains. Challenging mountain terrain awaits.

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 over 6, 600m of elevation gain across the 100-mile course, this race will punish those who are not prepared. 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. Welcome to Sinister 7 Ultra — a race that may be the greatest challenge of your life.

In 2022, we will be running the Sinister 7 Ultra course in reverse. This comes with great logistical challenges, which is why we have not done it sooner, but with great challenge comes great reward!
