While the Atlanta Marathon is not the hilliest race I have encountered it definitely took me by surprise as to how hilly it was for a race in a big city. I would not recommend trying to run the Atlanta Marathon for a personal best, HOWEVER I would definitely recommend running the marathon for a great, big-city road race experience. It was very well-organized, well-set up, easy to get to using the MARTA public transportation system, and full of very friendly volunteers and great course support throughout most of the race.
