Course, rules and logistics

The route follows the Herbert Hoover Levee around Lake Okeechobee and is mostly a 10-foot paved asphalt path, with about 15 miles of hard-packed crushed shell double track. There are several brief roadway sections to cross canals and rivers. The course is exposed with no shade or tree cover. There are 22 designated crew access points and one official aid station at the halfway mark in Lake Okeechobee Park; that aid station is open during the race.

All runners must have crew support; solo self-supported cart runners must carry all supplies on their cart and meet specific requirements, including minimum liquids and calories at the start, a GPX track, lights, and a working cell phone with spare power. Road sections require runners to face traffic and use reflective safety gear. Time limits require reaching the halfway mark within 18 hours and finishing the loop within 38 hours. Electronic chip timing and live updates are provided. A portion of race revenue supports a local conservation charity. Visit the organization's website for the most recent information.
