The Inaugural 13.1 Marathon Atlanta was this morning - great race, I did much better than I hoped to. My aggressive goal was sub 1:50 and I went sub 1:45!
Felt good throughout but gave it my all - when I crossed the finish line I got dizzy for just a second so I know I gave it everything.
The splits are based on my GPS watch but it seemed to beep just before every mile marker and got a little further each time. My watch showed the course was 13.2. I am not 100% on the accuracy considering that. Not sure why, it always seems to be really consistent any other time.
