Overview
Earn your right to indulge to your heart’s desire on Thanksgiving Day with a run down and back up the Big Creek Parkway just outside Atlanta at the Tryptophan Half Marathon, 10K & 5K, which makes its 14th annual running on the morning of Thanksgiving Day in November 2024. Hosted by Five Star NTP, a locally based race management company, the Tryptophan Half is set to follow an out-and-back course that starts and finishes at Fowler Park, along Carolene Way in Cumming.
Course Description
From there, the course is a simple one — from the starting line, runners head out onto the Big Creek Greenway, a combination boardwalk and concrete trail that winds through the area known as Big Creek, along a 12-foot-wide path for most of the route. After they make the turn, runners then retrace their steps all the way back to Fowler Park for the race finish. The scheduled starting time for the race is 7:30 AM, and organizers plan to limit the race to 3 hours, which means you’ll need to complete the 13.1-mile run by 10:30 AM in order to be an official finisher in the race.
