A flat, fully supported 100K overnight festival loop in Northern Colorado
Other trail races within 66 miles
Run the flat 4-mile groomed dirt out-and-back loop on a 146-acre private property outside Eaton, Colorado until reaching 100K. Full aid station and crew access every 2 miles, plus sauna, cold plunge, food barn, and massage zone throughout the 24-hour event window make this an exceptionally well-supported 100K. A strong choice for a first 100K or for runners who want a supported overnight endurance challenge without technical terrain.
