From their website, a2a.net, which has lots of information under "TELL ME MORE":
Athens to Atlanta (A2A) is the oldest and most famous road skate in America. Starting in Athens, Georgia, participants skate through beautiful country roads and quiet suburbia before navigating city streets and triumphantly crossing the finish line in Atlanta's Old Fourth Ward Skate Park. The course is challenging and requires experienced road skating ability, courage and stamina. Skaters who may not be ready for the whole 87 miles may opt for the 38-mile event, which also starts in Athens, or the 49-mile event, which starts near Dacula, GA. Inline and quad skaters are welcome and anyone from 8 to 80 years old may enter.
Roadskater.net inline skaters have done A2A as many as 18 times in a row. Familiar names can be found on the A2A Duraskaters (Distance) records page.
