From the Organizer
A fresh take on trail running that ditches the big-budget hype for pure, no frills adventure. Forget the lottery entries, $200+ fees, swag bags, and finish line blow up arches. This is trail running stripped back to what it should be: you, the dirt, friends new and old, and zero corporate polish.
We're keeping it deliberately low-key because running shouldn't cost a mortgage payment. Entry fee is only $50 bucks for any distance. You can change your desired distance the day of the race if you choose, just make sure you finish.
