Expect the Cooper River Bridge Run and Walk to be used for studies on an increasing basis in future years.

Dr. Harry Davakos, a professor of sports management at The Citadelís health, exercise and sports science department, left the Bridge Run board in 2010 after a 13-year stint. Since he is no longer affiliated with the Bridge Run, he is able to conduct studies on it and build data on the race.

Last year, Davakos conducted the third economic impact study on the event and the first since 2007. He plans to conduct an economic study every two years and other studies in between.

ďThere are other impacts of the Bridge Run that arenít economic,Ē Davakos said.

The 2011 study was based on 2,658 survey responses in the four days after the 34th annual Bridge Run. It focused primarily on the 63 percent identified as tourists, or those who lived 60 miles or more from the Charleston area, because they are more likely to spend money on hotels and food.

Of the total respondents, 83 percent were runners and 17 were walkers, with 64 percent were female and 36 percent male.

Highlights include the following:

$18.3 million: Total direct impact

$1,096,477: Total entrance fees

$4.2 million: Hotel income (based on 53 percent of travelers or 18,181 people)

$4.6 million: Fancy

$3.7 million: Casual/dine-in

$2.3 million: Fast food

$189,102: Expo revenue (due to sponsors who donít sell products and limited space at the Gaillard Auditorium)

11 percent: $200,000 or more

36 percent: $100,000-$200,000

36 percent: $50,000-$100,000

45 percent: College degree (four years)

25 percent: Masters degree

6 percent: Doctoral (or equivalent)

23 percent: First time

41 percent: 2010

33 percent: 2009

83 percent: Number who said they would participate in 2012
