Denver is a wonderful city for running. At the foothills of the Rockies, the ‘Mile-High City’ is graced by 300 sunny days a year. Easily accessible from a continually improving downtown is an excellent variety of paths, waterways, and parks. Our guide to the best places to run in Denver, Colorado includes the Cherry Creek path and Platte River trails, City Park, Cheesman Park, and some lovely residential areas. Nearby, there are also some great opportunities for trail and hill running, before things get really serious in the mountains. With the combined elevation and sun, be extra cautions about hydrating.
