Run Atlanta “404 Day” 5K is the ultimate kickoff to Atlanta’s 404 Day celebration—a high-energy experience blending fitness, culture, and community.

On April 4, we’re taking over Underground Atlanta in the heart of Downtown for a full day featuring a 5K race, 404 Day Parade, health & wellness activations, and a festival-style block party that keeps the vibes going long after the finish line. The race begins and ends at Underground Atlanta and follows a scenic out-and-back route through Downtown and Castleberry Hill, showcasing iconic views of State Farm Arena, Mercedes-Benz Stadium, and the fast-developing Centennial Yards. Most importantly, this celebration is powered by purpose—100 Black Men of Atlanta is the Official Beneficiary of the Run Atlanta 404 Day 5K.
