The August 22nd event takes 1,000 participants on a tour of the city that is part scavenger hunt, part obstacle course and part urban adventure race. You can also throw in a dose of humiliation (think strip bowling -- or live band street karaoke).
Teams will run, walk, crawl and use the CTA to navigate their way throughout the city during the 4-6 hour event, while using whatever means they can for help -- from family, to the internet to the kindness of strangers.
The entry fee is $190 per team. Visit citychaseusa.com for more information.
And remember your mom's advice about always wearing clean underwear -- especially before you go bowling.
