The Grand Prix of Denver is a former Champ Car race held on a street circuit in Denver, Colorado. A Champ Car race was first held in Denver in 1909 on a 14.5-mile (23.3-km) road circuit in nearby Brighton. Racing returned to the Centennial Park dirt oval in 1951 and 1952 under AAA sanctioning. 38 years later Champ Cars returned to Denver with a CART-sanctioned event downtown near the Civic Center. However, like the previous incarnation, that race also lasted only two years. CART returned to Denver in 2002 with a race on a 1.64-mile (2.64-km) temporary circuit around Pepsi Center. The final race was held in 2006. Champ Car initially put the race on its 2007 schedule but removed it after conflicts with other events could not be reconciled.
