The course

Course line from the race's own GPX. Source file. Year of this file not known.

A little under 16,000 feet of climbing across ridges and valleys in the Canadian Rockies, mostly single track. It follows the 50 mile route up Moose Mountain, then carries on to the Fullerton loop before returning to Paddy’s Flats.

The race

What this one is

Mountain races on the trails near Bragg Creek in Kananaskis Country, Alberta, run each August: a 100km, a 50 mile (also a 2 or 3 person relay), a 60km and a night-time 25km. The 50 mile, 60km and 100km start together at 6am from Paddy’s Flats Group Campground. The course climbs Powderface Ridge, Ford Knoll and Moose Mountain on single track, with views of the Canadian Rockies. Entry is capped at 200 runners.

For 2025 the start and finish moved from Station Flats to Paddy’s Flats Group Campground, because Alberta Parks was redeveloping the Station Flats day use area. The date moved from August 9 to August 16 that year to fit the campground booking.

Crew rules
Crew can meet runners at any aid station but not outside aid station areas. Aid stations 5 and 6 are only reached by walking about a mile from the upper Moose parking lot. A Kananaskis Conservation Pass is needed to park. ironlegs.ca
Pacer rules
Pacers are allowed starting at aid station 6. Runners can have one pacer at a time and pacers can switch at aid station 7. All pacers need to sign a waiver and pick up a bib at package pickup or the start/finish area. ironlegs.ca
Drop bag rules
Drop bags go to Elbow Aid Station 2, Powderface Aid Station 4 and Fullerton Aid Station 7. Drop them off at race check-in. ironlegs.ca
Cutoff philosophy
The cut-offs are for runner and volunteer safety. A runner who misses the Pneuma junction or Moose Packers cut-off is sent to the finish and ranked for the 60km. Racers who drop down in distance are still eligible for awards if they are in the top three. ironlegs.ca
