Miami 100

Miami 100 is an urban open-road ultramarathon in Miami, Florida, organized by Running Ninja Events. The 100-mile race threads through Wynwood, Miami Beach, Key Biscayne, Calle Ocho, Coconut Grove and Brickell, along streets and pedestrian paths with vehicular traffic. There are no traditional aid stations; runners rely on checkpoints and directional cards to reach the next point, with crew support required for first-timers (one vehicle per runner).

The course map is revealed gradually at checkpoints. A 125-mile add-on and a 50k Ride the Wave are also offered. Limited to 60 runners, with a 32-hour cutoff; it’s a Badwater 135 qualifier. Visit the organization's website for the most recent information.
