The course is based on a 16.7 km loop. Events use multiple loops to compose longer distances: 100K equals six loops, 50K equals three loops, 20 Mile equals two loops, and 10 Mile equals one loop. The 5K follows the first 5 kilometers of the loop. There is a 15 hour cutoff listed for the 100K event.

A marked Castle Climb behind Squire's Castle is optional for several distances; the climb is 0.15 miles each way and participants who complete it receive a token to carry to the finish for event swag. Aid stations are located at the start/finish area and near mile 5 and provide water, electrolyte drink, pretzels, candy, PB&J, salt tabs, and similar items. Registration includes a custom race shirt or an upgrade option, a finisher medal, a race bib, chip timing, and post race snacks. Awards are listed for top three female and male finishers in the main distances and 100K finishers receive a belt buckle.

Early packet pickup is available the day before at 2nd Sole Lakewood and on site packet pickup will be open during the event. Participants who begin a loop later in the day must carry a headlamp or other light source. Visit the organization's website for the most recent information.
