I'm so glad we did it! What a great time. We took the train to Lenox Mall in Buckhead then found our starting wave near the end of the pack. Wave W, which didn't hit the starting line until almost 9am. By this time it was already getting hot and we decided neither one of us were aiming for any personal bests. So our strategy was to run a mile, then walk a mile while we rehydrated.
The thing about the Peachtree if you're serious about running, you want to be seeded in the first waves. Otherwise you'll spend most of the race dodging the thousands of walkers and slower runners. It was much less frustrating today just going with the crowd while talking and laughing -- and sometimes dancing -- the entire way.
Happy Independence Day!
