Greenland Trail Races

The Greenland Trail Races, held annually in May at Greenland Open Space in Larkspur, Colorado, offer four race distances: 4 miles, 8 miles, 25K, and the 50K ultramarathon, known as Colorado's fastest 50K. The course features wide, smooth dirt trails through native grasslands, rolling oak hills, and ponderosa pine forests, with scenic views of Pikes Peak. The 50K and 25K races involve multiple loops, while shorter distances have single loops.

Participants enjoy a festive atmosphere with fully stocked aid stations, professional chip timing, finisher medals, technical shirts, and post-race pizza. The event is beginner-friendly and includes awards for overall and age group winners. Visit the organization's website for the most recent information.
