Tour du Colorado
The USA Pro Cycling Challenge, also known as USA Pro Challenge, was an annual multi-day professional road bicycle racing stage race that first took place in Colorado in 2011. Originally announced on August 4, 2010 by Colorado Governor Bill Ritter and Lance Armstrong as the Quiznos Pro Challenge, the event carried on the state's cycling legacy, which was most notably highlighted by the Coors Classic that ran from 1980 to 1988. On February 4, 2011 Richard E. Schaden, founder of Quiznos and the event's co-chairman, announced the investment of an initial $10 million to secure the initial growth and longevity of the race. The USA Pro Cycling Challenge was one of only three current 2.HC rated races in the United States (along with the Tour of California, and the Tour of Utah), and was considered one of the most important pro cycling races in the U.S.
