Sinister 7: July 13-14

100-miler • 50-miler • 50k • Relay

Welcome to 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 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.

We have three distance options: the 100-mile, the 50-miler, and a 50 km.
