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 (branded Publix Atlanta Marathon for sponsorship reasons) is an annual marathon held in Atlanta, Georgia, except in 2021 where it was held in Hampton, Georgia on the premises of Atlanta Motor Speedway because of governmental restrictions. On the same day, a half marathon is also held, and some years also feature a 5K run. Wikipedia
