LINCOLN, Neb. — Nebraskans are invited to participate in the second Cowboy Ultra, a two-day race that will guide runners (solo and relay teams) across the 191 miles of the Cowboy Trail from Valentine to Norfolk.

The Cowboy Ultra will take place on May 20-21. The event, organized by Angry Cow Adventures, is limited to 75 people. Registration is $70 per person.

For more information on the Cowboy Ultra, or to register, visit https://www.raceregister.net/event?action=view&id=290 or call 402-432-3622.

The Cowboy Trail is the longest former stretch of railroad to be converted into a trail in the United States.

Runners in the Cowboy Ultra can simultaneously take part in the Nebraska 150 Challenge. The Nebraska Sesquicentennial Commission, in honor of the state's 150th birthday in 2017, is inviting Nebraskans to complete 150 miles or more of physical activity – running, walking, biking or paddling – by the end of the year.
