Challenging course! All trail – some packed dirt, some looser rocks. Started at just above 4000ft with 3000ft elevation gain to the halfway point, then back down. It was mostly a fast hike for me, coming from flatland Florida, and although technically difficult, the course provided amazing views. Brought my hydration pack which was necessary. Recommended for those who want more of a challenging course.

This is a tough trail run with a 2,100 feet elevation gain then loss. The course starts out with a 1.5 mile flat / downhill run which helps improve overall pace, then it’s about 5 miles straight up a mountain across creeks and traversing mountain sides, requiring lots of speed hiking for even above average runners; however, once at the top, it’s 3.5 miles FAST downhill across rocky ridges and a compact, single-track dirt trail to the finish. At the finish line, I was greeted by a great cheering section but most importantly, free food and beer! 🙂
The shirts are nice but really nothing more is offered and the race bibs are plain-Jane, cheap-looking with basic numbers with no pictures or frills. The swag isn’t bad, there just isn’t much, if that is your thing.
