Finishers of this year's Akron RoadRunner Marathon crossed the finish line months ago, but the revenue generated by the race has only recently been tallied.

The economic impact is set at $5.2 million.  That's a 30% increase over last year's $4 million economic impact.  The numbers were crunched by the University of Akron's Department of Economics.  They consider things like money spend on hotel rooms, restaurants, even bottles of water.

The race attracted more than 13,000 participants in September, including more than a third that came from other areas to run in what's become considered one of the nation's premiere marathon events.

The study also found that 3.1 tons of materials were recycled following the race.

Registration for the begins for the 10th annual race on January 10.  The race is slated for September 29.
