The course

Where it goes multi-loop · 22 aid stations · rust marks a stop your crew can reach

Three laps of the 50 km Lethbridge river valley loop after an extra opening loop, finishing at Softball Valley. Finish within 33 hours. A 100 mile finish within the limit qualifies for the Western States lottery, but you must finish the race you start: stopping after 100 km does not count.

Each lap crosses about 16 hills (coulees), most of them 150 to 250 feet. In the 50 km lap there is 36 km of single track, 2 km of pavement, 5 km of gravel road and 7 km of shale path. The course is mostly exposed, with about 20% tree cover. Past the 4.5 km water station on Leg 4, help may take 2 hours to arrive and cell coverage is spotty.

The race

What this one is

The Lost Soul Ultra runs in the Oldman River valley in Lethbridge, Alberta, over a 50 km loop of coulees, single track, shale path and river bottom with about 16 hills per lap. A 50 km, a 100 km and a 100 mile all start and finish at Softball Valley, and the 100 km and 100 mile are Western States qualifiers. The race is small, run by volunteers, and finishers get an etched rock.

The Lost Soul Ultra was founded in 2000 by a group of ultrarunners. It grew from a small 40-person event where everyone received a sandwich at the end of the race. The original goal was to offer the toughest (and nicest) race on the Prairies.
