Southernmost Half Marathon & 10K

In October, runners will converge on the southernmost island in the United States and enjoy a break from the ordinary. Southernmost gives runners a choice of 13.1 or 6.2 miles of ocean and gulf views, as well as iconic Key West landmarks. Join us this fall in Key West. Come for the race and stay for a great time! All participants will receive an event t-shirt at packet pick up and finisher medal after completing the race.

The half marathon 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. There is a 3.5 hour time limit for the half marathon.

The start and finish for the Half Marathon and 10K are at the Lagerheads Bar in Key West, FL. Proudly brought to you by Integrity Multisport™. When you race, be sure that you “Race with Integrity™”.
