Imagine running through the southernmost island in the United States while enjoying a break from the ordinary.  The Southernmost Marathon & Half / Key West Running Festival promises just that- 26.2, 13.1 or 3.1 miles of ocean and gulf views, as well as iconic Key West landmarks. Join us this fall for Key West and the Florida Keys premier race- the Southernmost Marathon & Half. Come for the race and stay for a good time! All participants will receive an event t-shirt at packet pick up and finisher medal.

This fast and flat course takes you off of the island of Key West, through Stock Island, and up to US 1 for a turnaround. Once back on the island the Gulf of Mexico greets you to help you finish your race. There is a 6 hour time limit for the marathon. Please be advised that we will have a sweep vehicle if you do not finish in this time allowance.

The Half takes you off of Key West and onto Stock Island for the turnaround. On the way back, the Gulf side of the island provides water views for a majority of the way.  Water stations will be available but unmanned after 12pm. 

The start and finish for the Marathon and Half Marathon are at the Lagerheads 0 Simonton Street, Key West, FL.
