review of 2016 Chicago Marathon.   

5 / 5 Stars

Review

It was a great race. Great seeing all of the different communities, and all of the support from the city. The only thing I didn't like was the finish, spectators couldn't see the finish.

Race Tips

I took my own water bottle, it made it easier getting through the water stations. Get to your starting corral early.

Great crowd support, distractive surroundings, pancake flat course, very organized race

Race Tips

Get to start line early, don't start out to fast, miles 14-20 are a little boring so save energy for these, give it your all at the end.
