The inaugural USA Pro Cycling Challenge drew more than 1 million spectators and harvested $83.5 million in economic impact.

A study of the race, released Tuesday at the Capitol, showed that more than 20 percent of spectators at the Aug. 22-28 race came from outside the state. Even better: More than 94 percent of attendees surveyed said they were planning to return for next year’s race.

“All of the sudden, Colorado has jumped to the top of wish lists for people around the country and the globe,” said Al White , director of the Colorado Tourism Office.

Televisions in 161 countries flickered with images of Colorado, and nationally, NBC broadcast 25 hours of race coverage. The network recently proposed a multi-year contract to continue its coverage of the race.

“People from 161 countries saw the true awesomeness of Colorado,” said Denver Mayor Michael Hancock, who for Tuesday’s announcement joined mayors from the 10 other cities that hosted the race. “This was the most demanding competitive bike race in America, and that is something worth celebrating.”
