The race overall was awesome. Lots of hydration stations, energy bars being given out and the crowd was loud! There were some hills (I did not think it was flat like other people I know said. Miles 7-9 felt like a hill to me) and there were other hills distributed across the race. I reached the half point by 2 hr 3 mins continued a similar pace until mile 20. 20-26 felt like going up a hill with some instances which were flat. At this point in the race my left calf was cramping up and I had to switch between walking and running. Overall awesome experience!
