First Rock 'n' Roll for me and crossing off Illinois! Expo was vast, took lots of pictures and got some merchandise. Stayed at a hotel close to start line so it was a quick walk in the morning. Being a July race it was muggy when we started, but then started to rain with a total downpour at times which was I think better than running in humidity and heat. The course was very flat, but the bridges got a bit slippery. The Blue mile was to remember fallen heroes was a surprise and very emotional. Running through the city along famous landmarks was great, downside of big city running was the GPS was all messed up so pacing was a bit off for me. Aide station had water, Gatorade and one had gel. For a Rock 'n' roll didn't have as many bands, could be because of the weather that day. I did not stay for the after party so not sure how that went. walked past the "Bean" after for a photo opp which was nice!
