The Elkhorn 100 is a now-defunct race that started at the World's Largest Elkhorn Arch in Afton, Wyoming and finished 100 miles later at the elkhorn arches on Jackson Hole's Town Square.  The race was held in 2022 and 2023.  Due to heavy permitting requirements coupled with very limited participation the race is no longer being held.   The  supported-FKT is currently held by Cody Draper with a time of 27:35 in 2022.
