USA Cycling or USAC, based in Colorado Springs, Colorado, is the national governing body for bicycle racing in the United States. It covers the disciplines of road, track, mountain bike, cyclo-cross, BMX and collegiate racing. In 2009, USAC has a membership organization of nearly 66,800 members

USA Cycling is associated with the UCI, which governs international cycling and the United States Olympic Committee (USOC). The organization is also a member of the continental body Confederacion Panamericana de Ciclismo (COPACI).

The Amateur Bicycle League of America was organized in 1920 and incorporated in New York in 1921. In 1975, the name was changed to the United States Cycling Federation. In 1995, USA Cycling, Inc. was incorporated in Colorado, and on July 1, 1995, the two corporations merged, with USA Cycling the umbrella corporation. The office of USA Cycling, Inc. remained on the United States Olympic Training Center campus near downtown Colorado Springs until March 2009. Thanks to the generous support of Nor’wood Development group and the El Pomar Foundation combined with the collective efforts of the City of Colorado Springs and several local organizations including the Colorado Springs Economic Development Corporation and the Colorado Springs Sports Corporation, the national governing body secured office space on the city’s north side. USA Cycling’s new headquarters now consists of a 26,000-square-foot building on nearly two acres of land near I-25 on the northwest side of Colorado Springs.

Aaron Holmes Gwin is an American professional downhill mountain biker from Morongo Valley, California. He is recently known for breaking on to the international World Cup scene after about 8 months of riding downhill. Many see Gwin as the savior for US downhilling on the international scene since his 10th place finish at the Mont Sainte-Anne World Cup in 2008 was the first American top 10 finish since 2004.

Aaron Gwin started his cycling career off early racing BMX from age 4. By age 8 Gwin was racing all the nationals. At age 12 Gwin moved on to motocross and raced up until he was 17 when he quit due to constant injuries. In 2008 at age 20 Gwin was loaned a bike by fellow professional downhill racer and good friend Cody Warren and was encouraged to compete in a race. In his first race in the Fontana Winter Series he got 3rd and began racing from then on, quickly signing with Yeti Cycles. He has since won two United States National Championships for Downhill, in 2009 and in 2010. Both were held in SolVista, Colorado
