Coming October 26, 2019. Get in the Halloween spirit with the Miami Beach Halloween Half Marathon and the Freaky 4-Miler! The race starts early (6:30am for the half marathon and 6:45am for the 4-Miler), but before you balk at the time, it means that you’ll get to see the beautiful sunrise on the clear, blue-green waters of the ocean. Both courses are fast and mostly flat, covering the boardwalks and esplanades along the Atlantic Ocean. No matter whether you run or walk, everyone gets a coveted, signature Halloween themed medal. Though costumes aren’t mandatory, you gotta wear one if you’re running in a Halloween run! Dress up for the Miami Beach Halloween Half Marathon and the Freaky 4-Miler!
