Coming Soon!

Participant Handbooks! Each race distance will have a handbook. Participants are responsible for all information in the handbook. All race rules and regulations will be listed, as well as important race information, CREW and Pacer information, and maps.  The handbook will be a download document. There will be NO paper handbooks available at race registration so be sure to print your copy before traveling to Wyoming.  2019 Handbooks will be available on or before June 1, 2019. 


In 2019 we will provide every participant with a handy HYDROPAK collapsible race cup to carry with them to use for ALL liquids consumed on course. There will NOT be any cups, bowls, etc on course. All participants must show that they have the provided cup or something that holds liquids at start check in before each race. 

ATTENTION 52 mile alumni!

52 mile race becomes a true 50 miler in 2019!

Cut off times remain the same, start will be relocated to Devils Canyon Road.   Start location to be announced at a later date.
