About the Endure Trail Runs

The race takes place inside Mueller State Park on trails that are entirely unpaved, a mix of wider paths and narrow singletrack through the park. Several distance options run alongside a timed event with an unusual format: runners draw colored balls from a bucket, each one determining the next loop. Your result is simply how far you got before time ran out. The fixed-distance courses carry a generous cutoff.

An aid station sits on course, and the organizers describe it as worth lingering at. Race-day registration is available at the venue. Entry into the state park requires either a valid state parks pass or a day-use fee paid at the gate on the way in.
