About this race

Merus Adventure Park, located in the Palo Duro Canyon offers huge elevation gains throughout the land. The base elevation at the rim of the canyon is 3,412 feet above sea level. The lowest point on the floor of the canyon at MERUS Adventure is 2,500 feet. Most of the elevation gains range from 100 to 500 feet in drop, creating ample opportunities for a challenging race course.  Millions of years of erosion have created incredible colors and a variety of surface materials. As you cover the miles, you’ll traverse sand, sandstone, red dirt, rock, stone, clay, and witness some of the most amazing views! Come to Merus Adventure Park and take in the views at the Merus Marathon!
