Though city dwellers may feel a little crowded as they watch 45,000 runners brave the annual Bank of America Chicago Marathon, the runners and their families and entourages last year boosted the city’s economy by $219.7 million — the most in the event’s history — by staying in local hotels, shopping and sightseeing, ordering pre-race pasta dinners and otherwise being tourists, according to a report to be issued Wednesday.

That’s equivalent to creating 1,520 full-time jobs and $74.58 million worth of wages and salary income, according to the study done for Bank of America by the Regional Economics Applications Laboratory at the University of Illinois at Urbana-Champaign.

The $219.7 million total marked the first time business activity exceeded the $200 million level and was 28 percent greater than the impact in 2010, the study showed.

Each dollar spent by a race participant generated another $1.29 worth of activity, the report said.

“The world comes to Chicago for the marathon — not only elite runners, but running clubs, people running for charity and others pursuing their personal bests,” Bank of America spokeswoman Diane Wagner said.
