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

A night race. It starts at 8:30pm, climbs about 700 metres and runs a lollipop route out to the Fullerton aid station and back to Paddy’s Flats, with a 2am finish cut-off.

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.
