Lost Soul Ultra

Lost Soul Ultra is a trail ultramarathon in Lethbridge, Alberta held the weekend following Labour Day, with race dates listed as Sept 10–11, 2027.

The event offers multiple distances:

50 km
100 km
100 mile

The course runs through river valley coulees on public and private land. The 50 km route contains about 1,100 meters of total elevation gain and loss and includes 16 significant hills. The valley terrain includes deep coulees that can resemble a canyon. The 50 km course has three aid stations spaced so segments vary from about 7 to 16 km.

Field size is kept limited to roughly 350 participants. Organizers maintain smaller event size to preserve the race experience. Top finish times reported for past events are just over 4 hours for the 50 km, about 10 hours for the 100 km, and about 19 hours for the 100 mile.

The event is a qualifying course for Western States for the 100 km distance; the 100 km qualifying time is under 21 hours and the 100 mile qualifying time is 33 hours. Racers and pacers must be at least 18 years old. Runners registered for the 100 mile distance may not drop down to the 100 km during the race.
