Glacier Hills Ultra 50K
Canton, SD • November 1, 2025
Glacier Hills Ultra gives runners the chance to take the next step to a longer distance as it provides race distances of 20 km, 30 km, and 50 km. We have a hard cutoff of 8 hours for all 3 races to finish! Since we start at 6am all runners must be done by 2 pm (horses are not allowed on the course until after 1:30) if for some reason horses do get onto the trail before the set time make sure to notify us so we can alert the park rangers. Our volunteers are limited on their ability to stay and help so we need to be strict with this. If the time cut off is an issue please message the directors. This race is just a fun event and a break from the daily grind of being a farmer, teacher and probation officer. This is not our full time job. Sometimes our communication is great, sometimes overwhelming and other years next to nothing. We thank you for choosing to run with us and see the secrets that Newton Hills holds!
