Autumn Leaves 50/50
Announcement
This classic and fast ultra returns from the grave in 2025! Come join us as we celebrate!
Course Description
The course is a 10k loop consisting of 80% paved bike path and 20% dirt single track. It is built for speed as the course is very flat with some small rollers for fun. 50K runners will complete 5 loops and the 50-milers will do 8 loops. Despite the trail section, the whole course is typically runnable in road shoes. You will need a headlamp for your first lap, as it WILL be dark.
Working up to running ultra distances? New in 2025, sign up for the 30k, and run 3 loops with a later start time. Kids can join us for a free Kids Run (pre-registration required).
Pacers and Crew
All runners participating in the 50k race are allowed to have a pacer for the last 2 loops, and all runners participating in the 50 mile race are allowed to have a pacer for the last 3 loops. Pacers must sign a waiver and wear a pacer bib, and are welcome to use the aid stations. They may not mule (carry supplies) for their runner.
Support crew access is at the start/finish, and at the mid-course aid station near Oak Grove.
