The course

Where it goes point to point · 22 aid stations · rust marks a stop your crew can reach

Course line from the race's own GPX. Source file. Recorded 2026.

Seven legs from Blairmore to Coleman, ranging from 10.9 km to 31.7 km. The route crosses the Frank Slide debris field, climbs Hastings Ridge and Willoughby Ridge, runs beside Mount Tecumseh and goes around the base of Crowsnest Mountain on the way past Seven Sisters Mountain. Solo runners start at 7:00 am on Saturday and have 30 hours.

The race rates Leg 6, Crowsnest + Seven Sisters, 7 out of 7 and Leg 7 as 1 out of 7. The highest point is on Leg 6. The race says to expect wet feet on Legs 2 to 6, and a runner who cannot finish in 15 hours will be running in the dark. Expect hot, exposed stretches by day, cold at night, and bears, cougars and wolves in the area. The trail types are paved road, gravel road, double track, single track and high alpine.

The race

What this one is

A mountain ultra through the Rocky Mountains of Crowsnest Pass, Alberta, with a 100-mile, a 50-mile, a 50 km and a half marathon. The 100 miles are split into seven legs, each built around a landmark of the area such as the Frank Slide and Seven Sisters Mountain, and can be run solo or as a relay of up to seven people. Solo runners have 30 hours for the 100 miles. The race is named for the Seven Sisters mountain that looms over much of the course.

The first Sinister 7 was run in 2008. The course has changed over the years: an original course from 2008 to 2010, a 148 km course from 2011 to 2013, and then a 100-mile course. In 2022 the 100-mile course was run in reverse.

Crew rules
A support crew is not required but is recommended for solo runners. Crews can meet runners at every transition area, which are reachable by vehicle, but should not meet them at checkpoints. sinistersports.ca
Pacer rules
Pacers are not allowed. A runner may run with a registered competitor who is on the same leg, and anyone may join a runner within 300 m of the end of a leg. sinistersports.ca
Drop bag rules
Solo runners may leave a drop bag at each transition area, and teams may if they need to. TA2 and TA3 share a bag, as do TA5 and TA6. Bags are checked in at Friday race package pick-up. 100-mile bags are not accepted on Saturday morning. sinistersports.ca
Cutoff philosophy
The race says its cutoffs are strict, with a couple of minutes of leeway at the race director's discretion in extreme circumstances. A team that will miss a cutoff can take a forced start and keep running as unranked. The cutoffs exist to keep a 30 hour race running smoothly. sinistersports.ca
