Lots of miles and lots of views!
From the event website: "Utilizing the beautiful trails that surround Aspen, offering two options, a full or heavy half-marathon, both run almost exclusively on dirt trails. The diversity of terrain, challenging ascents & descents and overall elevation gain will challenge even the most well-trained athletes. With spectacular views of the Elk Mountains above and the city of Aspen below, this is one race you’ll be sure to remember! And…there is over $8,000 in cash and prizes."
