Fall brings sweater weather, pumpkin-flavored everything, and a beautiful racing season. And on November 9th, it’s time for Autumn Trails Eugene. This race, brought to us by Level 32 Racing, is the fifth event in the Run Big Trail Series (RBTS) and it’s a unique opportunity to see what you’ve got in the tank.

This race has 3.5 miles, 6 miles, 10 miles, or 16 miles to choose from and the courses are considered “organic” which means the length of the trail determines the length of the race, so the distances are approximate.
The event takes place near Frank Kinney Park in South Eugene off the Alpine Loop in the meadow. The races begin at 10AM with staggered starts in descending order of the distances. All courses will start with a loop on the Rexius Trail between Martin and Snell Street. All will climb up the Amazon Headwaters Trail to Fox Hollow Road.
There are 5 aid stations on the course at the major trailhead junctions. Runners can expect water, GU Brew, GU Energy Gels, and some light snacks.
Autumn Trails Eugene $25-$45
