New Year's Run 5K/10K/13.1 MIAMI

New Year's Run 5K/10K/13.1 MIAMI takes place in Key Biscayne, Florida, on December 26, 2026, with the half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run all starting at 7:30 a.m. There is no timing chip and no standard to worry about; runners and walkers share the same morning. Entry includes a gift bag with a race shirt and a finisher medal, and a virtual option is available.

A flat island setting and an early start make this an approachable first half marathon, and the absence of chip timing removes most of the temptation to go out too fast. Build for ten to twelve weeks with one long run each week and 13.1 miles becomes a manageable target rather than a leap. Anyone in town for the holidays can take the 5K instead and still be back before the rest of the household is up.
