Crew and pacer policies vary by distance; some distances allow crew at the start/finish while others restrict crew access, and pacers must carry required gear and complete a gear check where permitted. A portion of race proceeds supports the open spaces and trails of Castle Rock and partner charities. Each distance has published cutoff and time limit policies; the 50K has a 9-hour time limit.
