For those interested in outlying examples in the extreme, the 8-day Annual Great Bicycle Ride Across Iowa known as RAGBRAI takes more than 15,000 riders [1] on a different route across Iowa every year with different participating overnight communities selected each year. It is the "largest bike-touring event in the world" [2] "The University of Northern Iowa Sustainable Tourism and Environment Program conducted a (2008) study of RAGBRAI's economic impact on the state, and found the event generated nearly $25 million in direct spending. For overnight stops like Coralville and the points in between, that could mean more than $3 million a day in tourism spending."
