Miami 100

Miami 100 is an urban ultramarathon event in Miami, FL on September 26, 2026, organized by Miami Ultra Race Series. The course travels through city streets, pedestrian paths, and sidewalks and passes neighborhoods such as Wynwood, Miami Beach, Key Biscayne, Calle Ocho, Coconut Grove, and Brickell. The route includes historical and scenic areas, farmlands, Ocean Drive, and other city landmarks. All pre-race and post-race activities take place at Hero Martial Arts in Palmetto Bay.

The event emphasizes crew support and navigational challenge. There are no aid stations, only manned checkpoints; runners follow directional cards to reach each checkpoint. The course map is not released in full beforehand: the first segment is provided on race morning and additional segments are handed out at checkpoints located approximately every 15 to 20 miles. Runners who have not previously finished this event must have a crew; crew is limited to one vehicle per runner. The Miami 100 has a 32 hour cutoff. The Miami 130 Challenge adds 30 miles immediately after the 100 and has an overall 40 hour cutoff; entry to the 130 requires completion of the 100 within its cutoff. The Ride the Wave 50k has a 12 hour cutoff. Race fields are limited. Visit the organization's website for the most recent information.
