The courses use rolling singletrack and nontechnical trail segments. Distances may vary slightly each year due to permitting. A portion of race proceeds benefits the open spaces and trails of Castle Rock and partner charities.
Support on course includes two cup-free aid stations that runners will pass multiple times depending on distance. Aid stations provide water, an electrolyte drink (Tailwind), sweet and salty snacks, and fruit. Runners may leave a weather-sealed drop bag at the start/finish area. Crew access rules vary by distance; for example the 25K course does not allow crew except as assigned volunteers at aid stations. Pacers are permitted on specified segments and must carry required gear and complete a gear check before pacing.
Event services listed for participants include official chip timing, a custom finisher award, finish-line photography, and live split tracking across the race weekend. Registration closes Monday, August 24 at 11:59 PM Mountain Time, and a race goodie is guaranteed for registrations by August 10. Visit the organization's website for the most recent information.
