The Chicago Marathon was my first marathon and, I gotta tell you, I can't imagine a race being much better than this one. It's so well organized, the swag is great, and people cheer you on the whole time. People who had run it before warned me that the crowd might thin out a lot between miles 20-24, but I felt like there were people cheering the whole time. Running through the diverse neighborhoods really kept me going. There were plenty of aid stations and I felt that the start/end of the race were very well conceived. A note of advice that was given to me: pee before you go to the corral and then try not to stop until you're well into the race. Lots of people had to go right off the bat and there aren't many options until after Lincoln Park. Also, with the massive number of spectators and runners, it's easy to miss your peeps. Have your friends and family tell you what side of the street they'll be on so you don't miss them. Overall, I thought this race was incredible and I look forward to doing it again with a Charity team this year!
