Our return to Horsethief!

It's that time! We're returning to Horsethief Canyon with a Half Marathon!
Thank you for your patience with Forestry's fire security race postponement. The decision to close forestry services during peak fire months makes sense, Horsethief was the site of a fire last year even. But now with the reopening at the end of November we'll be ready to start up the Horsethief Half Marathon. Use the extra time to train extra hard and get a new personal best!

The Course

The course is an out-and-back on a dirt Fire Road - mostly uphill until the turnaround then mostly downhill back to the Finish. A great course to come out and run a negative split! The fire road is very wide, and not very technical, footing will be good no matter what the weather brings. A volunteer will be taking numbers at the turnaround to verify you made it

This race course is located in the Pine Creek Wilderness with permissions granted by the U.S.F.S. so be sure to respect the course and the surrounding lands.
