First time this year and it was awesome. Beautiful course, everything is extremely organized, water and gatorade every mile. I wouldn't have minded if they had another powerbar gel station earlier (mile 10 or so) as the only one is at mile 17, but was fine to carry my own nutrition. Finisher medals and shirts were also very classy. Parking in the Copley Square garage was easy, if not a little pricey, but as expected. Expo was jammed - they really need a bigger venue for that. Plan to return in the future!
