Atlanta Marathon
Race Day Weather
Cool start — fast day potential, big temp swing
A cool 42°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temps will climb significantly to 64°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info
The Atlanta Marathon is one of Georgia's largest road races, drawing roughly 16,000 runners across the marathon, half marathon and 5K each year in downtown Atlanta. Its historic course was known for sustained rolling hills between miles 8 and 18, and the half marathon has served as the USATF Half Marathon Championships in 2025 and 2026. Starting with the 2027 edition, the race moves to a new March date and an entirely new downtown course, replacing the Mercedes-Benz Stadium start used through 2026. The men's and women's course records, 2:18:50 and 2:41:12, were both set in 2008 by Oleg Marusin and Alena Vinnitskaya. Wikipedia
