For more than a century, the greatest race car drivers in the world have gathered at the Indianapolis Motor Speedway to compete in its premier race, the Indianapolis 500. This coming Sunday, 2021 NASCAR Cup Series champion Kyle Larson will make his second start in The Greatest Spectacle in Racing while pursuing one of racing's most arduous undertakings in the process.

Larson will try once again to become the fifth driver in history to race in both the Indy 500 and NASCAR's Coca-Cola 600 at Charlotte Motor Speedway in the same day -- known as The Double -- as he looks to complete all 1,100 miles on arguably the single biggest day in U.S. motorsports. 

One year ago, a rain delay at Indianapolis thrust Larson's attempt at The Double into chaos as he was forced to choose between committing to the Indy 500 and fulfilling his NASCAR obligations. Larson chose to stay at Indy, finishing 18th after starting fifth, and then flew to Charlotte in an attempt to at least get in his car mid-race and run the remaining laps of the 600 after reserve driver Justin Allgaier started Larson's car in his place. But another rain storm stopped the 600 at lap 249, preventing Larson from ever making a single lap in his Cup car and ruining his first try at The Double.

Should the weather cooperate this year, Larson will start the Indianapolis 500 from the 19th spot, and his presence in the field continues a long tradition of NASCAR crossovers in IndyCar's feature event dating back to the 1960s. Cale Yarborough, Bobby Johns, Lee Roy Yarbrough, and Bobby and Donnie Allison were just a few of the NASCAR greats to race in the Indy 500, and the Wood Brothers also made their mark on Indianapolis with their famous pit crew. But starting in the 1990s, when lights were installed at Charlotte Motor Speedway and the Coca-Cola 600 was moved to evening time, it became possible for drivers to compete in both the Indy 500 and NASCAR's longest race on the very same day.

"I travel around so much and race and fly in last minute for sprint car races and jump straight in and I think that will help the mindset of what it will be like for the 600," Larson told NASCAR.com this week.

"I think for sure, for me it's not like a culture shock at all to be here and then traveling around to race. It's what I do every week. Time windows are tight so often, so it doesn't seem any different than a normal weekend for me."

Ahead of Kyle Larson's second try at The Double, here is a complete overview of the history of the Indy-Charlotte Double, with each driver to have attempted and completed the feat.

1994 -- John Andretti 

After making his Indy 500 debut in 1988 and racing full-time in CART from 1990 to 1992, John Andretti -- the nephew of Mario Andretti -- made the switch from open-wheel cars to stock car racing in 1994, joining car owner Billy Hagan's team to run the full season in the NASCAR Winston Cup Series. But given his and his family's ties to Indianapolis, Andretti still desired to race in the Indy 500. And with that, Andretti would become the first driver to ever compete at both Indianapolis and Charlotte on the same day, developing a travel itinerary to make it happen.

Andretti qualified 10th for the Indianapolis 500 driving an A.J. Foyt-owned Lola, and he also qualified in the top 10 for the Coca-Cola 600 in ninth. After finishing 10th in the 500, Andretti flew to Charlotte in time for the start of the 600, but only completed 220 of 400 laps before suffering a crankshaft failure and finishing 36th.

Andretti would also compete in the inaugural Brickyard 400 at Indianapolis later that year, becoming the first driver to ever run both the Indy 500 and Brickyard 400 in the same year.

1995 -- Davy Jones

Following Andretti, IndyCar veteran Davy Jones intended to do the Indy-Charlotte Double in 1995, driving for Dick Simon at Indianapolis and Jasper Motorsports in NASCAR. However, Jones' plans were foiled when he failed to qualify for the Coke 600, leaving him to settle for only running the Indy 500 and finishing 23rd.

1997 -- Robby Gordon

After going to NASCAR full-time in 1997 with Team SABCO, Robby Gordon's initial plans of doing a pure Indy-Charlotte Double would also be foiled, but that was due to the effects of Mother Nature. Rain forced the Indianapolis 500 to be postponed to Monday, leaving Gordon to fly to Charlotte and run only the Coca-Cola 600 on Sunday, completing 186 laps before crashing and finishing 41st.

Gordon started 12th at Indianapolis on Monday in a car owned by Felix Sabates -- also his car owner in NASCAR -- making 15 laps before more rain pushed the rest of the race to Tuesday. Gordon only made it four more laps before his car caught fire, leaving him with a 29th-place finish.

1999 -- Tony Stewart

Tony Stewart made the switch from open-wheel to NASCAR after winning the Indy Racing League championship in 1997, first running the NASCAR Busch Series alongside the IRL in 1998 before heading to the Cup Series in 1999 with Joe Gibbs Racing. He would wind up doing the Indy-Charlotte Double for the first time in his rookie season, qualifying 24th and finishing ninth at Indianapolis for Tri-Star Motorsports before heading to Charlotte for the 600. Stewart wound up leading 13 laps in the 600 and finishing fourth.

2000 -- Robby Gordon

Robby Gordon tried the Indy-Charlotte Double again in 2000 for car owner John Menard, but inclement weather would again wind up altering his plans. Gordon qualified fourth at Indianapolis driving for John Menard and 42nd at Charlotte, but rain delayed the start of the Indy 500 by several hours and prevented Gordon from starting his car in the Coke 600. Backup driver P.J. Jones started Gordon's car at Charlotte while he finished sixth and Indianapolis, and he then took over for Jones midway through the Coke 600 and finished 35th.

Despite running his Cup car at the finish of the Coke 600, Gordon did not go into the record books as having run both Indy and Charlotte on the same day. Per NASCAR rules, P.J. Jones was credited as the driver of the No. 13 Ford and received championship points by virtue of having started the car.

2001 -- Tony Stewart

Stewart would pull double duty again in 2001, and he would proceed to go a distance that go racer had ever gone before. Driving for Chip Ganassi at Indianapolis, Stewart would qualify seventh and lead 13 laps on his way to finishing sixth, then flew to Charlotte and finished third in the Coke 600.

With Stewart finishing on the lead lap at both Indy and at Charlotte, Stewart would end up becoming the first -- and to date, the only -- driver to ever complete all 1,100 miles of racing during the day.

2002-2004 -- Robby Gordon

After joining Richard Childress Racing in NASCAR, Robby Gordon ran the Indy-Charlotte Double three years in a row from 2002 to 2004, with his best outing coming in 2002 as part of a collaboration between Team Menard and RCR. Gordon finished eighth in that year's Indy 500, then flew to Charlotte and finished 16th.

Driving for Andretti Green Racing the next year, Gordon qualified on the front row at Indianapolis in third, but he failed to finish after suffering a gearbox failure and then ran 17th at Charlotte. Rain was again a theme in Gordon's final Double attempt the next year, as rain midway through the Indy 500 kept him from finishing the race before he had to fly to Charlotte for the 600. Relief driver Jacques Lazier got in Gordon's car at Indianapolis, finishing 29th due to a mechanical failure after 88 laps, while Gordon ran 20th at Charlotte.

2014 -- Kurt Busch

The most recent driver to complete the Indy-Charlotte Double was Kurt Busch in 2014, who ran IndyCar for the first time ever when he partnered with Andretti Autosport. Busch took to open wheel immediately in his first and only IndyCar start, qualifying 12th and finishing sixth in the Indianapolis 500 before flying to Charlotte to take the wheel of his No. 41 Cup ride for Stewart-Haas Racing. Busch ended up suffering an engine failure after completing 271 laps in the Coke 600 and finished 40th.

2024 -- Kyle Larson

One year ago, Kyle Larson's much anticipated Indianapolis 500 debut saw him qualify fifth before taking care of his NASCAR obligations, running fourth in the All-Star Race at North Wilkesboro before qualifying 10th for the Coke 600 in Charlotte. But on Sunday morning, Larson's plans of starting both races were foiled when rained delayed the start at Indianapolis, forcing Larson to miss the start of the Coke 600 while he finished 18th at Indianapolis after a pit road speeding penalty.

While reserve driver and NASCAR Xfinity Series star Justin Allgaier started Larson's car at Charlotte and was credited as the driver of record, the plan was for Larson's Hendrick Motorsports team to make a driver change upon his arrival in Charlotte, with Allgaier stepping out of the car and Larson getting in to complete the remaining laps of the Coca-Cola 600. But those remaining laps never happened. Just as Larson arrived at Charlotte Motor Speedway, so too did another rainstorm that stopped the Coke 600 at lap 249. The race never restarted and went into the record books as an official race having passed the halfway point, meaning Larson never made a single lap.

Allgaier would be credited with a 13th place finish, and Larson would have to be granted a waiver from NASCAR in order to remain eligible for the playoffs despite having missed a race. Larson would earn a measure of redemption on his next trip to Indy, as he would win the Brickyard 400 when NASCAR visited Indianapolis in July.
