We are also excited to announce that in place of the 16-mile option from years past, we will be hosting Wyoming's first and only (as of right now) true Backyard Ultra, made famous by the one & only Gary Cantrell (Lazarus Lake)
Skunk Hollow Sneaker Chase & Backyard Ultra 2025 will be Saturday July 19th!

Course description

Set amidst the beauty and serenity of Casper Mountain, on forested XC ski and single-track trails. Choose from a challenging 8 mile (2 - 4.17 mile laps) or Backyard Ultra - the same 4.17-mile lap, run every hour on the hour until there is just one runner left standing. Each event starts/finishes in the same location along the Natrona County Parks Multi-Use Trail System.
With course elevations ranging from 7800-8100 feet, this fun yet challenging course will surely enhance what you thought were limitations.
