Overview

The Glacier Hills 50k Ultra, organised by Sioux Falls Area Running Club (SFARC), takes place in Canton, SD, in November. This 50k trail race has been run for 10 editions since 2016.

With a time limit of 8 hours, the Glacier Hills 50k Ultra has a tighter cutoff than 80% of 1019 comparable 50k races. This means runners must maintain a pace faster than 9.6 minutes per kilometer to finish within the allotted time. The race features a 10km loop course through the Newton Hills State Park trail system, starting and ending at the second bridge near the picnic shelter.
