About the race
Cowboy 100 is a 100 mile trail race scheduled for April 17, 2027 in Valentine, NE, organized by Ultraverse Supplements. The event is a point to point route that starts in Valentine and finishes in Atkinson and is limited to a field of 150 runners.
The course follows the Cowboy Trail, a former rail trail surfaced with crushed limestone and closed to automobiles. The trail is nontechnical, described as 100 percent runnable and largely flat. Because the 100 mile route will run the second half of the 200 mile course in reverse, course records from the original Cowboy 100 will not transfer.
Planned full aid is scheduled at Arabia, Wood Lake, Johnstown, Ainsworth, Long Pine, Bassett, and Stuart, which reduces the average distance between aid stations. The race offers live GPS tracking by Legends Tracking USA and a shuttle option for uncrewed runners. The official cutoff for the race is 34 hour.
Finishers of the 100 mile race will receive new buckle hardware for 2027. The event supports a Cowboy Hall of Fame program in which runners who accumulate 1000 miles between the Cowboy 200 and Cowboy 100 are inducted and receive a commemorative buckle and ongoing entry benefits.
Entry policies include no refunds and no bib transfers. Deferrals are permitted for race credit on a sliding scale based on how far in advance the deferral is requested. Registration closes on March 22. Visit the organization's website for the most recent information.
