One of the largest single-day sporting event in history is the Indy 500. The running of the Indy 500 has been going on since 1911. The 93rd running of the race will take place in May of 2009, making it the 64th consecutive year without interruption. Other names of the race throughout history have been the International 500-Mile Sweepstakes (twice), the International 300-Mile Sweepstakes and the Liberty Sweepstakes. The race has been carried on television and radio. It debuted on radio in 1952 on the Indianapolis Motor Speedway Radio Network. The firs time the race was televised from start to finish was in 1986 by ABC.

The race is held at the Indianapolis Motor Speedway, which was built in 1909. Its first track was a gravel and tar track which was then changed to all brick and then pavement. The first Indy 500 took place on May 30, 1911. The venue currently holds approximately 400,000 people. The first race was seen by just over 80,000 people who paid $1 for admission. The first race included Ray Harroun, the inventor of the rear view mirror. The race was originally an open event which meant that anyone could race in the event if they wished to do so. Now the race is by invitation only. Drivers must qualify for participating in the event.

When the race was an open event the qualifying procedure entailed the admission fee and maintained a certain speed was allowed to join the field. The order of start was determined at random, by determining who handed in their signup forms first. Now the qualifying, since it is by invitation only, is a little tougher. The current speed-based qualifying was started in 1915 and the field was limited to 33 entries, which is still the case for today's race. The qualifying process today consists of a four-lap distance and it was introduced in the year 1933.

With each race comes traditions at the Indy 500 from year to year. The most popular tradition, and most popular words in sports aside from "Play Ball," is "Gentlemen, start your engines!" Other traditions include the detonation of an explosive to signal the opening of the arena's gates at 6am on the day of the race, "Taps" is played to symbolize the remembrance of Memorial Day along with a flyover, "God Bless America" is performed by Florence Henderson and "The Star-Spangled Banner" is performed by a different popular artist each year.

There have been a multitude of accidents during the running of the Indy 500 and a handful of deaths involving drivers, crew, spectators and driving mechanics (which haven't been used since the early years of the race). The last death during the Indy 500 was in 1973 when Swede Savage died on July 2nd in a hospital from injuries suffered in the race. Some believe that Savage might have died do to contaminated blood from a transfusion. Savage was the 14th driver to die either at the race or after the race to due injuries from an accident or from heat exhaustion.
