Autumn Trails Eugene is the season finale of the Run Big Trail Series, and it’s a celebration of everything we love about trail running in the Pacific Northwest. Crisp fall air, golden leaves, and the rolling Ridgeline Trail system create a course that’s as scenic as it is challenging.

Whether you’re a first-timer dipping your toes into trail running or a seasoned mountain goat looking for a longer grind, this race has a distance that fits. With staggered starts and plenty of space to find your rhythm, runners can settle in, breathe deep, and enjoy the last burst of color before winter settles in.

Visitors and crews will find plenty to cheer for at trail junctions and the finish near Frank Kinney Park. The atmosphere is welcoming, festive, and full of that South Eugene running community energy that makes you want to come back year after year.
