Our Story

Sinister Sports has hosted world-class endurance events throughout Alberta and British Columbia for nearly 20 years. Our promise is that we will always challenge you and offer the best organized events for our athletes. We want you to know the Rocky Mountains the way we see them. Bold, grand, and beautiful, but gritty and daunting. Our flagship race, Sinister 7 Ultra is a 100-mile run that takes you through the southern Alberta Rockies around Crowsnest Pass. The Canadian Death Race is new to our lineup and we are excited to be the hosts of this prestigious, iconic ultra that takes racers across the wilds around Grande Cache, Alberta. Black Spur Ultra offers 54k and 108k distances on a course that is all trails with big climbs and superb scenery. We only host events that will challenge you to the core; not for the weak of spirit!
