I loved everything about this race except that there was no expo. They mail you your bib and you pick up your shirt on race morning. Love that there is a shuttle to the start and back which moves very quickly. The spectators were encouraging and helped get me over the hills ... yes, it is a hilly course for this Chicagoan. The Adidas long sleeve shirts are excellent quality and fit perfect. The gear check was very well staffed and the volunteers throughout the race were wonderful. The medal is cute ... and a nice addition to my collection. Stayed at the Copley Square Hotel which is walking distance from the bus shuttles and in the heart of everything. Great hotel for an even greater race. The race started at 8 am and the temps were in the 30s and didn't feel much warmer when I finished. Overall I rate this race a 10 for a wonderful experience. Boston has an "old" feel to it and the race allowed me to see it all. Loved the nature as we ran through and around the zoo.
