Skunk Hollow Sneaker Chase
Casper, United States • 18 Jul 2026
About the Event
The Skunk Hollow Sneaker Chase & Backyard Ultra is a trail running event held on July 18, 2026, in Casper, Wyoming. The event location is the Casper Mountain Trails Center. Participants can choose between two formats: an 8-mile trail run (consisting of two laps on a 4.17-mile loop) or a Backyard Ultra "last runner standing" event on a single 4.17-mile loop. The event is officially listed in the Big's Backyard Ultra database.
Course Information
The 8-mile course direction alternates each year: in even-numbered years (like 2026), the run proceeds clockwise. For odd-numbered years, it runs counter-clockwise. In the Backyard Ultra format, the direction for each lap is determined by a coin toss.
Registration
Registration is handled online. The first 75 total registrants across both events receive a race souvenir with their registration; this souvenir is not available after the first 75 sign-ups. Standard registration fees are $50 for the 8-mile event and $60 for the Backyard Ultra. Prices increase on June 18, 2026, and again for registrations the day before the event. There is no race day registration. Due to upfront costs, no refunds or rollovers are given for registration. Visit the organization's website for the most recent information.
