Cowboy 100 - April 17, 2027
Cowboy 100 is a point-to-point 100 mile race organized by Ultraverse Supplements. The course runs from Valentine to Atkinson along the Cowboy Trail, a crushed limestone rail-trail that is off-limits to automobiles. The trail is described as non-technical, fully runnable, and very flat.
The 2027 edition separates the 100 from the Cowboy 200 and retains a field cap of 150 runners. The 100 will follow what has been the second half of the 200 in reverse; finishers hardware will feature a new buckle design for the 100-mile race. Because the route is technically new, course records from the original Cowboy 100 will not transfer.
Planned full aid stations are located at Arabia, Wood Lake, Johnstown, Ainsworth, Long Pine, Bassett, and Stuart, reducing the average distance between aid to about 14 miles. The event includes live GPS tracking by Legends Tracking USA, a 34 hour cutoff, and a shuttle option for uncrewed runners. The exact route is subject to change due to trail closures or maintenance.
The event policy states no refunds and no bib transfers. Entry deferral is allowed with race credit according to deadlines: 100% if deferred at least three months prior, 75% at least two months prior, 50% at least one month prior, and no deferrals after March 17. Registration closes March 22. Visit the organization's website for the most recent information.
