Run Santa Run Atlanta

Run Santa Run Atlanta takes over downtown Atlanta, Georgia, on December 13, 2026, with three road formats: a 5K, a 10K, and a half marathon (13.1 miles). The race runs in a festive end-of-year atmosphere, past the holiday light displays of the city center, and plenty of entrants line up in full Santa costume.

A city-center course keeps pacing simple, and the half marathon rewards a 12-week build with one long run each week climbing toward 11 miles. The 10K is the middle ground for runners with a solid base who want a hard hour of work, while the 5K is short enough to enter on a whim. Whichever you choose, remember that a costume adds heat: dress lighter underneath than instinct suggests.
