Southernmost Half Marathon and 10K 2026

The Southernmost Half Marathon and 10K begins and ends at Higgs Beach in Key West, situated on the southernmost island of the United States. Participants can select either a 10K or a half marathon, accommodating those seeking a shorter road race and those targeting 13.1 miles. The course is flat and fast, offering ocean and gulf views, and it is not a Boston qualifier. The route incorporates Key West itself, featuring island landmarks rather than a standard out-and-back course. The participant count typically ranges from 1,000 to 5,000, providing an event atmosphere without the congestion of a major city race. Integrity Multisport is the organizer, and the event embraces its "Race with Integrity" theme; participants receive a shirt at packet pickup and a medal upon completion.
