The course

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

A solo-only course that starts from York Creek Staging Area in Coleman, runs a 13.9 km opening leg that joins Leg 4, and then follows Legs 5, 6 and 7 of the 100-mile course to the Crowsnest Sports Complex. Runners start at 10:30 am on Saturday and have 24 hours. In 2027 and 2028 it is the Athletics Canada Long Trail Championship race.

The race rates the opening 13.9 km leg 2 out of 7, Leg 5 4 out of 7, Leg 6 7 out of 7 and Leg 7 1 out of 7. The opening leg is described as fast and runnable, with a short stretch of single track about 1 km in. Leg 6 reaches the highest point of the course. Expect creek crossings, heat by day and cold overnight.

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 TA4 and at TA5/TA6, which share a bag. raceroster.com
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
