The race has been run annually since 1911 (with exceptions during World War I and World War II) and 71 drivers have been crowned champions of the 500-mile race over the course of 101 races. The most race victories held by a single driver is four, which has been accomplished only by A.J. Foyt, Al Unser and Rick Mears.
