Skunk Hollow Sneaker Chase & Backyard Ultra

Skunk Hollow Sneaker Chase & Backyard Ultra 2025 will be Saturday July 19th!

We are excited to announce that we will be back to our original start finish area near the new Casper Mountain Trails Center (9301 Casper Mountain Rd, Casper, WY 82601). So, all of our parking, start/finish, and post-race festivities will be taking place there.
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)
For those not sure, and or a little nervous about the Backyard Ultra option, fear not. We still have an 8ish mile option (2 lap) option for you.

A coin toss will determine each respective laps direction…
