About the race
The Greenland Trail Races take place at Greenland Open Space near Larkspur, Colorado on May 1, 2027. The event offers four trail distances that share a looped route on dirt trails through native grasslands, ponds, Gamble oak hills, and ponderosa pine stands with views of Pikes Peak and local buttes. The course follows part of the Colorado Front Range Trail and the Old Territorial Road. The high point of the main loop is the saddle at about 7,400 feet.
The 50K and 25K run multiple laps of the same loop; the 50K completes the loop four times and the 25K completes it twice. Aid stations are placed at about mile 3.5 and mile 7.5 of each loop and provide water and Gatorade. Gels are available for 25K and 50K runners starting on the second lap.
There are no aid stations on the 4 mile course. A portable restroom is located near the southern aid station. Race services include a gender specific technical shirt, a finisher medal, a belt buckle for 50K finishers, professional chip timing with a disposable bib tag, and free photo downloads after the event. Pacers are allowed only on the final lap of the 50K.
Crewing is permitted only at designated aid station locations. Packet pickup occurs the two days prior at Runners Roost locations in Colorado Springs and Lone Tree. Visit the organization's website for the most recent information.
