September always feels a little like a reset. The kids are heading back to school, summer is winding down, and we’re slowly edging toward those cooler fall mornings that runners love. The Oregon race calendar stays plenty busy, too, with everything from quick 5Ks and community runs to half marathons, ultras, trail races, and plenty in between.
As always, race details can change, so be sure to check the event page before heading out for the latest information on registration, courses, start times, and any other updates.
With fall racing just around the corner, September is a great time to find a new goal, shake off the summer chaos, and get back out there.
