Escape the winter chill and kick off your year with an unforgettable running experience at the Key West Half Marathon, 10K, and 5K, taking place on January 17, 2026, in picturesque Key West, Florida. This acclaimed event consistently ranks as one of the nation's best half-marathons by USA Today and Runner's World, drawing participants from across the globe to its vibrant island setting. Runners can anticipate typical race day conditions with highs around 75°F and lows around 63°F, accompanied by tropical humidity, making hydration vital throughout the course.

The flat, fast, and USATF-measured courses offer breathtaking scenery, with approximately 95% waterfront views for all distances. Beginning at Caroline Street & Trumbo Road, participants will weave through Key West's historic Old Town, past iconic landmarks such as the Southernmost Point, Ernest Hemingway's house, and the Key West lighthouse, with the ocean as a constant companion. The scenic journey culminates with a festive finish at the Waterfront Brewery in the Historic Seaport. Aid stations, stocked with water and Ultima Replenisher sports drink, are strategically placed every couple of miles, though runners are encouraged to bring their own refillable vessels for this cup-free event.

What truly sets the Key West Half Marathon apart is its lively atmosphere and unparalleled post-race celebration. Known for its enthusiastic volunteers and vibrant energy, the event promises custom finisher medals, gender-specific tech shirts, and a memorable party featuring live music, a rum tasting courtesy of Papa's Pilar Rum, and refreshing beverages. Beyond the traditional races, the weekend expands into a full "Runfest" with unique events like the Papa's Pilar Rum Stroll and the Beach N' Beer Mile, creating a destination race that blends fitness with pure island fun.
