High Quality Content by WIKIPEDIA articles! The Monterey Sports Car Championships (formerly named the Monterey Triple Crown) is a sports car race held annually at Mazda Raceway Laguna Seca. The event began in 1950 as a race on the roads of Pebble Beach, California. In 1951, it was added to the new SCCA National Sports Car Championship. When Laguna Seca Raceway was built in 1957, the races moved there. The event fell dormant after the National Championship was discontinued in 1957, but was revived by the SCCA's new United States Road Racing Championship in 1963. The race fell dormant again in 1969, and was revived in 1973 with the IMSA GT Championship. Since 1999, the event has been a part of the American Le Mans Series. Beginning with the 2010 edition, the race runs to a six hour duration.
