Courses are described as not overly technical and include repeated segments that provide varied terrain and views. A portion of event proceeds benefit the open spaces and trails of Castle Rock and partner charities. The event offers live split tracking and official chip timing, and finishers receive a custom award and finish line photo.
Support on course includes two cup-free aid stations that runners will visit multiple times depending on distance. Aid stations provide water, an electrolyte drink (Tailwind), sweet snacks, salty snacks, and fruit. Crew access is allowed at the start/finish area, and runners may leave a weather sealed drop bag at the start/finish.
