Join us for the 43rd running of the Horsetooth Half Marathon. Your race will take you from Hughes Stadium, the home of the CSU Rams, to the finish line party at New Belgium Brewery. On the way you'll tackle the challenging hills of Centennial Drive along the shoreline of the shimmering Horsetooth Reservoir, before you head for home on the downhill Poudre River recreation trail. Whether an elite runner or a first time half marathoner, the Horsetooth Half Marathon offers a challenging yet deceptively fast course.
