The Bank of America Chicago Marathon raked in more than $243 million in business activity last year, exceeding the revenue of its 2011 race.

A study conducted by the University of Illinois showed the event directly contributed $98 million to the tourism industry, in addition to an indirect contribution of $145.46 million. That's the equivalent of 1,685 full-time jobs and $82.66 million in wages and salary income.

“As one of the city’s premier events, the Bank of America Chicago Marathon really brings the city together,” Mayor Rahm Emanuel said. “It gives us an opportunity to proudly showcase our world-class hotels, restaurants and entertainment opportunities. I am appreciative of Bank of America’s efforts to support the Marathon, as evidenced by the growing interest and economic impact of the event.”

Last year's contribution is an 11 percent increase from the 2011 race, which had an economic impact of $219.7 million.

“Many people come to Chicago for the first time because of the Marathon, and they come from all 50 states and more than 100 countries,” Bank of America Illinois President Tim Maloney said. “Tens of thousands of people look forward to it every year, whether they’re running in the race, cheering on family and friends, or running a business that caters to these groups. We are proud to work hand-in-hand with Chicago officials and residents to ensure that every Marathon participant has a positive experience and wants to return next year.”

The 2013 race is expected to draw 45,000 runners and 1.7 million spectators.
