Flying Horse Half Marathon, 10k and 5k is presented by United Way of El Paso County and sponsored by the City of Sunland Park. The event will start and finish at Sunland Park Racetrack & Casino. This race is perfect for both first-time runners and experienced athletes who want to take on a new challenge or improve their time. This year, we'll also be having a family friendly Giddy Up Fun Run around the racetrack.
