The race started with a flyover and we were off on live runways! It was a clear Colorado morning, had a great start, no crowding and plenty of space to spread out. Finished my best time! Lots of giveaways and finisher medals. It's an added plus to know you're helping people

1st time competing in this race. From the easy to find parking lot right in front of the starting line and race expo area to the well organized volunteers, everything made this race fun and worthwhile. The course was well marked with water at every mile and road condition

Chicago is one of, if not the best marathon. The crowd is packed along the route, cheering on all of the runners the entire time. The course is almost entirely flat. The volunteers and workers are incredibly supportive and helpful and everything runs like clockwork. This was my 4th time running
