Jingle Bell Jog Key Biscayne

Jingle Bell Jog Key Biscayne is held on Key Biscayne, Florida, on December 19, 2026, with a single 5K starting early at 7:15 a.m. The one-distance format and the sunrise gun keep the event compact — you will be finished and back into your Saturday well before most people have had breakfast.

An early start on an island road generally means flat, fast running, which favors anyone chasing a personal best over three miles. The catch with a 7:15 a.m. gun is preparation: get up early enough to eat something light two hours out and to jog for at least 15 minutes before the start, because a cold body over a 5K costs more time than any pacing mistake. Two weeks of short, sharp repeats beforehand is the useful final touch.
