This was my first half marathon, and I couldn't have asked for a better experience. The weather was as good as can be expected for a Chicago summer morning. The on-course entertainment makes a huge difference. It really keeps you motivated throughout the race. The aid stations were great, plenty of Gatorade and water at each one, and cool, wet sponges being handed out in the later miles. The course is a beautiful run that really shows off stunning views of our city. Highly recommended.
