The 2014 Boston Marathon is poised to become the largest ever in history in many different respects. Race officials included an extra 9,000 participants in the field, while last year’s tragedy has prompted an outpouring of love and support. It appears, in that respect, as though everyone will be spending more money in the Greater Boston area than they have during any other Boston Marathon.

According to Greater Boston Convention & Visitors Bureau President and CEO Patrick Moscaritolo, the 2014 Boston Marathon is expected to bring in such a massive crowd that $175.8 million will be dropped by the time the last Marathon participant boards a bus back home.

“The spending impact of the 118th Boston Marathon provides a huge economic benefit for our visitor industry and it kick starts our spring tourism season,” said Moscaritolo in a statement.

This year’s 26.2 mile race will draw 35,660 official participants alone, not counting the influx of tourists and supporters to go along with those who live and work in the metro area. About 5,330 of them hail from over 70 countries around the world. Oh, and don’t forget about the more than 1,800 members of the media from more than 300 outlets.

The spending clout expected this year will succeed even the most financially successful Marathon in Boston Athletic Association history, the race’s centennial in 1996. Those attending spent over $172 million in our neck of the woods almost 20 years ago.

“The 2014 Boston Marathon will be a special event for all of the people of Greater Boston and our sport as a whole,” said B.A.A. Executive Director Tom Grilk in a statement. “The B.A.A. welcomes participants and spectators from around the world who will patronize Greater Boston’s shops, restaurants, hotels, and local businesses. This year, we will all come together to stand as one in celebration of the resilience of Greater Boston.”
