Miami 100 : September 26, 2026

The Miami 100 is an urban open-road 100-mile ultramarathon in Miami, Florida held on September 26, 2026. Registration for the 2026 event is open. The event is limited to 50 runners. Pre-race activities, the start area and the finish area take place at Hero Martial Arts in Palmetto Bay. There is a mandatory race briefing on the Friday before the race for runners and crew who have not previously participated.

Course, rules and additional challenge

The course uses pedestrian paths and sidewalks through Miami neighborhoods such as Wynwood, Miami Beach, Key Biscayne, Calle Ocho, Coconut Grove and Brickell. Runners will encounter vehicular traffic and must follow pedestrian laws. There are no aid stations; runners rely on checkpoints and crew support. Checkpoints are manned and placed approximately every 15-20 miles. Runners receive directional cards and the full course map is given in parts - the first portion on race morning and the rest at checkpoints as runners progress. Crew rules: first-time finishers of the Miami 100 must have a crew; crew is limited to one vehicle per runner. Runners who previously finished the race may run unsupported using drop bags. The 100-mile course time limit is 32 hours. An optional Miami 130 Challenge adds 30 miles immediately after the 100-mile finish and has a 40-hour overall cutoff; entry to the challenge requires finishing the 100 within the 32-hour cutoff.

Distances:

  • 100 miles
  • 130 miles (100 + 30 add-on)
