The Experience
The Colbert Autumn Classic, hosted by the Bloomsday Road Runners Club, invites runners to the scenic back roads of Colbert and Green Bluff, Washington. This event, now in its 21st year, provides a perfect opportunity to tune up for fall marathons as the weather cools.
Runners can choose between the half marathon or a 4-mile loop, with both races starting at 9:00 a.m. An early start option is available for half marathoners expecting to finish in over 2.5 hours. The course is noted for its beautiful scenery and is described as being on the back roads, suggesting a more rural and potentially rolling terrain.
With a median field size of approximately 1,577 finishers, the event draws participants from around six states, indicating a solid regional draw. A hoodie sweatshirt and a finisher's medal are among the rewards for participants, adding to the appeal of this established fall classic.
