About

A Merry Christmas Run 5K/10K/13.1 MIAMI is run on Key Biscayne, Florida, on December 26, 2026, with a common 7:30 a.m. start for the half marathon (13.1 miles), the 10K, the 5K and a family one-mile fun run. The event trades competition for camaraderie, and the clock is your own business, tracked through a running app or ignored altogether. A race shirt, a finisher medal and a gift bag come with the entry.

Half marathons in South Florida in late December are popular for good reason, and this one keeps the format simple enough that visitors can enter without rearranging a trip. Treat it as a long run in good company if you are in a marathon build, or as a first 13.1 if you have twelve weeks of steady running behind you. Starting at 7:30 a.m. also means you are done with the race with the rest of the morning still ahead.
