Well run and organized despite the large numbers. Expo was easy to get to with provided bus transportation. Great freebies such as a Chi Marathon specific poster and a World Marathon Majors swag bag were nice, unexpected perks. Neat landmark specific finisher medals. Really nice finishers chute with numerous opportunities for post-race photos, nutrition such as protein shakes and bars, a bag of multiple snacks, gels, water, chocolate milk, gatorade and more. Quite a walk from the finish to bag pickup, but your legs will thank you for this the next day! Shirts were ok and not as nice as I would have expected of a Nike shirt. Many mats along the route make race day tracking for friends and family super informative. Even if you don't like crowds, racing Chicago is a bucket list item.
