Cowboy 100 - April 17, 2027
The Cowboy 100 is a point-to-point 100-mile ultramarathon held in Nebraska and organized by Ultraverse Supplements. The race runs from Valentine to Atkinson along the Cowboy Trail, a former rail-trail of crushed limestone that is off-limits to automobiles. The trail is described as non-technical, fully runnable, and very flat.
The 2027 event is the standalone 100-mile edition after the Cowboy 200/100 separation and is capped at 150 runners. The 100-mile course follows the second half of the former 200-mile route in reverse, and course records from the original Cowboy 100 will not carry over to this new routing. New finisher buckles are planned for the 100-mile race.
Planned full aid is located at Arabia, Wood Lake, Johnstown, Ainsworth, Long Pine, Bassett, and Stuart, which reduces the average distance between aid stations to about 14 miles. A 34-hour race cutoff is specified. Live GPS tracking will be provided by Legends Tracking USA. A shuttle will be available for uncrewed runners; further shuttle and aid station details will be provided in the runners manual.
Entry terms include no refunds and no bib transfers. Deferral options are available with varying credit amounts depending on how far in advance the runner initiates the deferral; no deferrals are permitted after March 17, 2027. The listed entry price is USD 487.80. Visit the organization's website for the most recent information.
