From the Organizer
Welcome to the 54th running of the Horsetooth Half Marathon, Presented by Fort Collins Connexion. Your race will take you on a scenic point-to-point journey from the location of Hughes Stadium, the former 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 shorelines of the shimmering Horsetooth Reservoir, before you head for the famed New Belgium Finish Line Party 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 surprisingly fast course, with a net loss in elevation.
