Course Overview
The Mace's Hideout 100 takes place in early June in Colorado's Wet Mountains near Beulah, with runners navigating a challenging course that offers views of the nearby Sangre de Cristo range. This is a demanding 100-mile effort with a 36-hour cutoff, featuring a mix of out-and-backs sections across the loop that bring you through the same aid stations twice—a format that can be mentally tough as you retrace familiar ground while fatigue builds. The course moves through varied mountain terrain, transitioning between forested sections and more exposed areas with climbing spread throughout. Fourteen aid stations provide regular support, with pacers allowed starting at mile 46 and drop bag access at key points. June conditions in this part of Colorado can bring afternoon thunderstorms and significant temperature swings from morning starts to midday heat, so weather preparedness matters. Runners who handle technical mountain terrain well and don't mind the mental challenge of repeated sections will find this race suits them. The aid station layout means you'll see other runners regularly, which some find motivating and others find distracting. Those looking for a straightforward point-to-point mountain experience might prefer different formats, but runners who appreciate the logistics and familiar checkpoints of this style will likely enjoy the challenge.
