Overview
The Lost Soul Ultra Marathon takes place the weekend following Labour Day in Lethbridge, Alberta. The trail course runs through the river valley coulees on public and private land. In this event, 350 ultra-marathoners race against each other, the elements, and the unrelenting hills. Less than 150 years ago, these valleys were the site of the last major First Nations battle on Canadian soil between the Blackfoot and Cree Confederacies. We are honored to share their land for our event.
The 50 km course includes three aid stations located at key points with segment distances varying from 7 to 16 km. Elevation gain or loss is approximately 1,100 meters with 16 significant hills over the 50 km lap. Although we are on the prairies, our river valley can feel like the Grand Canyon. Top race times are just over 4 hours for the 50 km, 10 hours for the 100 km and 19 hours for the 100 mile event.
The race organizers continue to keep the race small to maintain memorable running experiences. One racer commented: “Thank you to all the organizers and thanks and hugs to all volunteers, you made it possible for me to finish and enjoy spending time at each station. I will be back next year for sure.” Check out our Facebook page to read more racer comments and reports. Racers and pacers must be at least 18 years of age.
Lost Soul Ultra is one of the few Canadian races where you can qualify with a 100km finish.
Lost Soul Ultra has maintained its status as a 100 km qualifier for the Western States 100-Mile Endurance Run. 100 km qualifying time is under 21 hours. 100-mile racers can now qualify if they complete the 100-mile distance in 33 hours. *Note: runners cannot drop down from 100mile to the 100km during the race.
