LOCATION: Chicago, Illinois
DATE: October 13
There are many extremely well-organized major marathons across the country—Big Sur, New York City, and Marine Corps immediately come to mind—but none top the precision of the Bank of America Chicago Marathon. The route is wide, the water stations stretch long so there’s no congestion, and the pack spreads out quickly after the start line despite the more than 35,000 entrants. The race’s added bonus is that it gives you a chance to enjoy the city in the middle of October.
