Adventure Cycling Association

The Adventure Cycling Association ( ACA) is a non- cyclist Association in the U.S., which is currently about 44,000 members counts. Compared to the German ADFC the focus is more on the development and application of ( partly out ) bike tour routes, less on promoting the bicycle as an everyday means of transport. The headquarters is located in Missoula, Montana.

It was founded in 1973 under the name Bikecentennial. 1976 crossed a total of about 4100 cyclists on the occasion of the 200th anniversary of the Declaration of Independence, the United States from both directions on the Bikecentennial Trail (now the Transamerica Trail ), which drove about 2000 cyclists the entire route (some with sponsors help and support vehicles, partly independently as a self-catering ).

Currently, the ACA has developed a bike route network in the U.S., which includes about 41,400 miles total distance. The routing takes place mostly along quiet back roads, the routes are usually not marked and are traversed either by map or by GPS track.
