The Experience

The Tryptophan Half Marathon, now in its 16th year, has become a cherished Thanksgiving Day tradition in Cumming, Georgia. Runners and walkers gather to burn pre-feast calories, with options for a half marathon, 10K, or 5K, and even a 1K Fun Run. This event has seen about 277 finishers in recent years, with a growing field size and a loyal 18% repeat-runner rate.

The course is primarily on paved roads, with a flat profile that lends itself to fast times. While the official elevation gain and loss are minimal, the race is noted for its scenic elements, earning a 4.00 rating in that category. The atmosphere is one of community and family, with participants coming together to create special memories on a holiday focused on gratitude.

Participants can choose to run in-person or virtually. Packet pickup is available the day before the race and on race morning. The event concludes with post-race snacks and a finisher medal, with free photographs available to capture the day's accomplishments.
