From the Organizer
Get ready to totally rock the new courses coming to Fall Fest 2027! It's like trail running that's absolutely rad—with all the support, reliability, and killer experience you've come to expect from All-Out. These new courses are going to be awesome! Every distance will get to experience the wonderful Standley Lake Open Space and those tubular views of the Flatirons over Standley Lake. We're totally stoked to finalize the details with the venue, and we'll share the new course and venue by mid-January 2027. This is going to be gnarly!
