Key West Half Marathon & 5K

Sunday, January 17, 2016 • Key West, FL • Course Map

active-reg-buttonMore than 2,000 runners and walkers crossed the finish line in both races combined at the 2014 running of Florida’s Key West Half Marathon and 5K, which takes runners on a course to see the wildly colorful sights and sounds of this island at the far western end of the Florida Keys.

Fast, very flat and scenic throughout, the course for the race takes participants mostly around the edge of this, the easternmost island in the Florida Keys, and includes a bridge crossing over Key West’s Cow Key Channel to Stock Island and back, for a run around the Key West Golf Course and Country Club.

There’s also a stretch of the race that unfolds through CB Harvey Rest Beach Park near the White Pier, where you can get spectacular views of the sunset later in the day.

The out-and-back 13.1-mile course for the race starts and finishes at Dante’s Restaurant on Caroline Street, on Key West’s western end. From there, the course winds its way along several twists and turns through the city streets, turning on Duval Street, Eaton Street and Whitehead Street before hitting longer straightaways along Atlantic Boulevard and South Roosevelt Boulevard, which is also part of Florida Highway A1A.

Along the race route, runners have views of the ocean waters for virtually the entire course, and pass by local landmarks like the Key West lighthouse, famed author Ernest Hemingway’s house, downtown Key West’s “old town” area and the southernmost point in the United States.

The biggest elevation change during the 13.1-mile route are the stretches along Duval Street and Whitehead Street. Runners head over this hilly stretch twice — once going over and once coming back — and then head along Key West’s southern edge for the second half of the race heading back toward the finish line.

Even though the race takes place in January, it still typically sees relatively warm weather, so runners from climates where it’s generally colder during the season are encourage to stay well hydrated throughout the race, as aid stations will be available every couple of miles, with water and Powerade.
