The course

Where it goes loop · 2 aid stations

The full Miami 100: one continuous 100-mile trip through Wynwood, Miami Beach, Key Biscayne, Calle Ocho, Coconut Grove and Brickell, starting and finishing at Hero Martial Arts in Palmetto Bay. There is no map beforehand. Runners find each checkpoint from turn-by-turn directional cards, with their crew as the only support along the way, and 32 hours on the clock. A finish here is now an official preferred qualifier for the Badwater 135.

Flat, paved city streets and sidewalks with several bridges along the way. Runners cross active traffic throughout and must follow pedestrian laws. Reports describe late-September Miami as consistently hot and humid, and carrying ice from checkpoint to checkpoint is a common strategy.

The race

What this one is

An open-road urban ultramarathon through Miami, Florida, starting and finishing at Hero Martial Arts in Palmetto Bay. Runners cover 100 miles through neighborhoods like Wynwood, Miami Beach, Key Biscayne, Calle Ocho, Coconut Grove and Brickell, on sidewalks and pedestrian paths alongside active traffic. There is no course map beforehand: runners follow turn-by-turn directional cards handed out at manned checkpoints roughly every 15 to 20 miles, and rely on their own crew rather than aid stations. A Miami 100 finish is now an official preferred qualifier for the Badwater 135.
