Editing Indianapolis 500 (section)

==NASCAR and the 500==
In the 1960s and early 1970s, the Indy 500 and the [[Coca-Cola 600|World 600]] (now known as the Coca-Cola 600) at [[Charlotte Motor Speedway]] were held on different days of the week. A handful of [[NASCAR]] regulars participated in both events in the same year, including [[Bobby Allison]], [[Donnie Allison]], [[Cale Yarborough]], and [[Lee Roy Yarbrough]]. From 1974 to 1992, the two events were scheduled for the same day and same starting time, making participation in both impossible. A few stock car drivers during that time, namely [[Neil Bonnett]] in 1979, nevertheless still attempted to qualify at Indy, even if that meant skipping Charlotte altogether.

From 1994 to 2014,<ref>{{cite web|title=Kurt Busch Won't Attempt Memorial Day Double|url=http://www.nascar.com/en_us/news-media/articles/2016/3/23/kurt-busch-double-indianapolis-500-coca-cola-600.html|website=NASCAR.com|access-date=2016-07-05|archive-date=2016-06-28|archive-url=https://web.archive.org/web/20160628193911/http://www.nascar.com/en_us/news-media/articles/2016/3/23/kurt-busch-double-indianapolis-500-coca-cola-600.html|url-status=dead}}</ref> several [[NASCAR]] drivers were able to compete in both the Indy 500 and the [[Coca-Cola 600]] at [[Charlotte Motor Speedway|Charlotte]] on the same day. Since 1993, the Coca-Cola 600 has been scheduled in the evening the same day as the Indy 500. The effort has been known as [[Double Duty (auto racing)|"Double Duty"]].

After the Indy 500, drivers would catch a helicopter directly from the Speedway to [[Indianapolis International Airport]]. From there they would fly to [[Concord Regional Airport]], and ride a helicopter to the NASCAR race. [[John Andretti]], [[Tony Stewart]], and [[Robby Gordon]] attempted the feat, with [[Kyle Larson]] being the latest in 2024. In 2001, [[Tony Stewart]] became the first driver to complete the full race distance (1,100 miles) in both races on the same day.<ref name="INDY30">{{cite web

For 2005, the start of Indianapolis was pushed back to 1 p.m. [[Eastern Daylight Time|EDT]] to improve television ratings. This significantly closed the window for a driver to be able to race both events on the same day. (The race's original starting time had been set at 11 a.m. EST to 12 noon EDT—because in 1911, race promoters estimated it would take six hours to complete the event, and they did not want the race to finish too close to dinnertime. Nowadays, the race is routinely completed in under three-and-a-half hours.)

Two drivers, [[Mario Andretti]] and [[A. J. Foyt]], have won the Indianapolis 500 and the [[Daytona 500]]. Foyt also won the [[24 Hours of Daytona]] and [[12 Hours of Sebring]], America's premier endurance races, as well as the [[24 Hours of Le Mans]]. Foyt won Le Mans in 1967, about one month after winning his third Indy 500. Andretti won the {{f1|1978}} Formula One World Championship and is a three-time Sebring winner (he also won the 6-hour version of Daytona). Indianapolis 500 winner [[Johnny Rutherford]] once won one of the [[Gatorade Duel|Daytona 500 qualifying races]]. In 2010, [[Chip Ganassi]] became the first car owner to win the Daytona and Indianapolis 500s in the same year, with [[Jamie McMurray]] winning the Daytona 500 and [[Dario Franchitti]] winning the Indianapolis 500.

In 2010, [[Bruton Smith]] (owner of [[Speedway Motorsports, Inc.]]), offered $20 million to any driver, IndyCar or NASCAR, who can win both the Indianapolis 500 and the Coca-Cola 600 on the same day starting in 2011, a feat that had never been accomplished. For 2011, the Indianapolis Motor Speedway moved the start time of the Indy 500 back to 12:15 PM EDT (prior to 2005, the engines started at 10:52 AM EST; under the modern schedule, engines start around 12:05 PM for a start around 12:15 PM), which re-opened the window for travel. [[Brad Keselowski]] suggested that he would consider answering the challenge in 2014.<ref>{{cite magazine|magazine=Autoweek|url=http://www.autoweek.com/article/20130524/nascar01/130529855|title=Gunning for first NASCAR Sprint Cup win of the year in the Coca-Cola 600: Brad Keselowski's Autoweek blog|access-date=2013-07-28|archive-url=https://web.archive.org/web/20140305082344/http://www.autoweek.com/article/20130524/nascar01/130529855|archive-date=2014-03-05|url-status=dead}}</ref> It was announced on March 4, 2014, that [[Kurt Busch]] would attempt to qualify for the [[2014 Indianapolis 500]], driving a fifth car for the [[Andretti Autosport]] team.<ref>{{cite web|url=https://www.usatoday.com/story/sports/nascar/2014/03/04/kurt-busch-indianapolis-500-coca-cola-600-double/6008475/|title=Kurt Busch to attempt Indianapolis 500, Coke 600 'double'|last=Gluck|first=Jeff|date=March 4, 2014|work=[[USA Today]]|access-date=2014-03-04|location=McLean, VA|archive-date=March 5, 2014|archive-url=https://web.archive.org/web/20140305032058/http://www.usatoday.com/story/sports/nascar/2014/03/04/kurt-busch-indianapolis-500-coca-cola-600-double/6008475/|url-status=live}}</ref> Busch completed all 500 miles at Indy to finish sixth but dropped out of the 600 with a blown engine just past the 400-mile mark. In 2024, [[Kyle Larson]] attempted, but could not complete the double, racing with [[Arrow McLaren]] in the 500 and intending to drive with Hendrick Motorsports in the 600. Kyle Larson finished 18th in the Indianapolis 500 and arrived part way through the Coke Zero 600 due to a four hour rain delay at Indianapolis Motor Speedway. The 600 was red flagged for a thunderstorm shortly after Larson arrived at the track and was not restarted, with Larson not being able to participate.<ref>{{Cite web |date=2024-05-28 |title=As weather plagued the Indy 500 and Coke 600, Kyle Larson learned how tricky double duty can be |url=https://sports.yahoo.com/as-weather-plagued-the-indy-500-and-coke-600-kyle-larson-learned-how-tricky-double-duty-can-be-135959198.html |access-date=2024-05-29 |website=Yahoo Sports |language=en-US}}</ref>

For 2019, NBC Sports and the Speedway changed the start time. The engines started at 12:38 PM for a start time of 12:45 PM.
