Miami 100
Miami, United States • 27 Sep 2025
The Miami 100 is an urban ultramarathon held in Miami, Florida, featuring a challenging 100-mile course through iconic neighborhoods such as Wynwood, Miami Beach, Key Biscayne, Calle Ocho, Coconut Grove, and Brickell. The race is unique in that it is run on open roads with pedestrian paths and sidewalks, requiring runners to navigate using directional cards and checkpoints rather than a full course map, which is revealed progressively during the event. Crews are mandatory for first-time 100-mile participants, and there are no aid stations, only checkpoints. Additional events include the Miami 125 Challenge, adding 25 miles post-100 miles, and the Ride the Wave 50k, a 50-kilometer urban race. The race atmosphere combines urban exploration with endurance challenge, limited to 60 runners for the 100-mile and 50 for the 50k. Visit the organization's website for the most recent information.
