The Southernmost Marathon & Half

Presented by 361 Degrees

Saturday, October 7, 2017


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. SoMo Marathon is a USATF certified course.

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 Rum Barrel, 528 Front Street, Key West, FL.
