Autumn Trails Eugene

Prepare for an unforgettable trail running experience at the Autumn Trails Eugene, set to take place on November 8, 2026, in scenic Eugene, Oregon. This cherished event, the fifth in the popular Run Big Trail Series, offers distances of 3.5M, 6M, 10M, and a challenging 16M, with course lengths being approximate due to the organic nature of the trails. Runners will navigate the beautiful Ridgeline Trail system, renowned as a "south Eugene gem," starting and finishing near Frank Kinney Park.

The courses promise an immersion into "Autumn Splendor," featuring a variety of terrain that includes a loop on the Rexius Trail before climbing up the Amazon Headwaters Trail to Fox Hollow Road. The longer 10M and 16M routes extend further, with the 16M offering a more adventurous journey out to Blanton Heights and around the south side of Spencer Butte, Eugene's highest point at 2,058 feet. Expect picturesque scenery with Douglas-fir forests, Oregon white oak savannas, and hilltop prairies adorned with vibrant reds, oranges, and yellows of fall foliage. Aid stations, strategically placed at major trailhead junctions, will keep participants fueled with water, GU Brew, GU Energy Gels, and light snacks.

Typical race day conditions in early November include highs around 56F and lows around 39F, with a 23% chance of precipitation, creating that quintessential crisp autumn running atmosphere. The Autumn Trails Eugene has earned a reputation for being a very well-organized event with friendly and accommodating organizers, offering delicious post-race food, including vegetarian options.
