Obviously you run the risk of freezing your tail off but thankfully the course they have is through nice and quiet streets with small hills. The fact you can stay inside the gym before and race the race if it's real cold helps alot.

Would run this race again.

This was the 2nd year I ran the Chicago Marathon. Love the course, love all the spectators! This year there was an issue leaving Grant Park. Huge cluster of people trying to get back to Michigan Ave, all the gates prevented everyone from exiting smoothly. There was a lot of standing

Excellent and engaged entertainment and spirit throughout! Great balance of water and Gatorade and GU. Meaningful display of faces of the fallen. Neighborhood feel and support, from little kids with brownies to people lining the streets and sitting on their front porches. Dedicated
