Miami 100
The Miami 100 is an open road ultramarathon held in Miami, Florida on September 26, 2026. The event uses city streets, pedestrian paths, and sidewalks; runners will encounter vehicular traffic and must follow local pedestrian laws. The course passes through many Miami neighborhoods and landmarks, including Wynwood, Miami Beach, Key Biscayne, Calle Ocho, Coconut Grove, Brickell and Ocean Drive, and includes historical and scenic areas.
The event emphasizes independent navigation and crew support. There are no traditional aid stations, only checkpoints; runners reach checkpoints by following directional cards with step by step directions. The full course map is not released in advance: the first portion is provided on race morning and the remainder is handed out at manned checkpoints placed approximately every 15 - 20 miles. Runners are largely dependent on their crew; crew is limited to one vehicle per runner. Runners who have not previously finished the Miami 100 are required to have a crew. Previous finishers may elect to run unsupported using drop bags.
The race field is limited. The Miami 100 has a course time limit of 32 hours. Additional options during the same weekend include the Miami 130 Challenge, which adds 30 miles after finishing the 100 and has an overall 40 hour cutoff, and the Ride the Wave 50k, a point to point 50 kilometer event with a 12 hour course limit. Start and finish area activities are centered at Hero Martial Arts in Palmetto Bay. Visit the organization's website for the most recent information.
