Iron Horse Half Marathon is a running race on August 29, 2027 in North Bend, WA, with an entry fee of $107.
IMPORTANT FOR 2027: Damage to the Iron Horse trail from the December 2025 floods mean that no events are being held there in 2027, including the Iron Horse Half. Our course has been re-routed to adjust to this. The new course is a modified out and back, point-to-point route. While it is no longer downhill for the first 10 miles, the incline is mild and limited to the first few miles.
