Swim with the Miami skyline hovering overhead, and the famous Miami Beach close by. Taking place every April, Swim Miami takes participants near Palm Island and its multimillion-dollar homes, and the setting in Biscayne Bay makes the waters calmer than a typical ocean swim. The original Swim Miami debuted in 1989, and today, the distances of 10K, 5K, 1-mile and 800 meters attract nearly 2,000 participants annually.
