September 2025 signals a seasonal shift—but not a slowdown in racing. Labor Day Weekend has come and gone, school is back in session, and routines are settling in—but that’s no reason to hang up your running shoes. In fact, early fall is one of the best times to race in Oregon, with cooler temps, crisp mornings, and a full calendar of events.
Whether you’re eyeing a fast 5K, a scenic half, or a challenging trail race, there’s plenty to keep your race calendar alive and well this month.
