Greenland Trail Races

Greenland Trail Races is a multi-distance trail running event held at Greenland Open Space in Larkspur, Colorado. The lineup includes 50K, 25K, 8-mile, and 4-mile races, all run on dirt trails within the scenic open space, offering wide, smooth double-track surfaces and views of Pikes Peak. The course uses the Old Territorial Road and loops through native grasslands, Gamble oak hills, and ponderosa forests, with a high point around 7,400 feet.

The event features a festive atmosphere on course and at the finish, fully stocked aid stations, gender-specific tech shirts, finisher medals (belt buckles for 50K), free photos, chip timing, and post-race pizza. Visit the organization's website for the most recent information.
