Double Duty (auto racing)

John Andretti was the first driver to attempt "Double Duty" in 1994.

Double Duty[1] also referred to as the Indy-Charlotte Double[2] or Memorial Day Double,[2] refers to an accomplishment in automobile racing in which a driver competes in the Indianapolis 500 and Coca-Cola 600 in the same day. The feat was first attempted by John Andretti on May 29, 1994.[3] In 2001, Tony Stewart became the first and only driver to date to successfully complete all 1,100 miles of both races in the same day. The two races, organized by separate sanctioning bodies—IndyCar and NASCAR respectively—are held on Memorial Day weekend, and are considered two of the biggest annual events on the U.S. motorsports calendar.

The "Double Duty" calls for a driver to compete at the Indianapolis Motor Speedway in Speedway, Indiana in the early afternoon, then take an airplane to Concord, North Carolina to race at Charlotte Motor Speedway in the evening. The feat is considered difficult on face, as well as physically demanding and mentally draining. It is somewhat similar in concept to the established discipline of endurance racing, however, the driver is expected to drive both races in their entirety without the help of a relief driver.

Considerable media attention usually spotlights a driver who attempts the "Double Duty." The concept dates back specifically to 1994, but as far back as the 1960s, drivers have attempted to compete in both events when they were held on different days of the week. Also during the 1960s and 1970s, a handful of drivers raced at the Indianapolis 500 while maintaining a full-time schedule in Formula One. This would require them to travel between Indianapolis and Europe during the month of May, usually between Indy and Monaco, on an equally as demanding schedule.

Four drivers (John Andretti, Robby Gordon, Tony Stewart and Kurt Busch) have attempted the Indianapolis/Charlotte "Double Duty" feat. Of these, Tony Stewart's 2001 effort stands as the best combined result. He finished 6th at Indianapolis and 3rd at Charlotte, completing all 1,100 miles. Among the handful of drivers in the 1960s and 1970s that attempted "crossovers," Donnie Allison competed in both events in a year in which they were held on successive days.

To date, the most recent attempt was made by Busch in 2014. He finished in 6th place at the Indianapolis 500, and was the fastest rookie. However, he dropped out of the Coca Cola 600 with a blown engine mid-race. He completed 906 miles.

Logistics

Charlotte Motor Speedway, a quad-oval

The Indianapolis 500 is part of the Verizon IndyCar Series, and the Coca-Cola 600 is part of the NASCAR Sprint Cup Series. Both races are held, weather permitting, on the Sunday of Memorial Day weekend. The Indy 500 at the Indianapolis Motor Speedway is traditionally scheduled in the afternoon, while the Coca-Cola 600 at Charlotte Motor Speedway is held as a night race. Since the events are not scheduled to overlap, this allows a driver a small window to travel between venues.

Such an accomplishment can be grueling and physically exhausting. It calls for a driver to race for over seven hours in two entirely different disciplines of racing cars. Along with a 430-mile airplane flight, and severe time constraints, the driver has time for only a brief rest aboard the aircraft where he normally takes on IV fluids, and is checked out by a physician.

Weather plays a significant factor in the logistics of "Double Duty." If weather cooperates and there is no rain at either venue, delays are usually minimal. However, if rain delays one of the races (particularly Indianapolis), it can significantly disrupt or completely cancel the opportunity for the attempt.

According to NASCAR rules all drivers are required, without exception, to attend in person the pre-race drivers' meeting or suffer a grid penalty. If a driver misses the meeting for any reason, he is forced to start from last position on the grid. The meeting normally takes place approximately two hours before the start of the race (Coca-Cola 600), and under the circumstances of "Double Duty," the driver would have little or no opportunity to attend in-person. Despite attempts over the years to lobby the officials, including garage area petitions, and use of a video-conference device, drivers attempting "Double Duty" have all been required to start at the back of the grid for the Coca-Cola 600.

Month of May events

When a driver attempts "Double Duty," his complicated schedule is not just limited to race day. Additional flights back-and-forth between the venues are required in the two weeks leading up to the races in order to participate in practice and qualifying for the respective events. Time trials for the Indy 500 are held on Saturday and Sunday one week before the race. This potentially creates conflicts with the NASCAR Sprint All-Star Race. Qualifying for the Coca-Cola 600 is held on Wednesday night, while Carb Day, the final practice session at Indy, is held on Friday. Typically drivers are also obligated to make appearances for sponsors and event marketing in the days leading up to the races, which can add to the travel burdens.

Itinerary

Tony Stewart's 1999 Indy car used in his "Double Duty" attempt

A driver attempting the "Double Duty" has an extremely busy and tight schedule, particularly for race day. The morning begins in Indianapolis, and at the conclusion of the Indy 500 (or when the drivers drops out of the race), he immediately travels from the Speedway (via helicopter or police escort) to a nearby airport - Eagle Creek, Indianapolis International, or another in the vicinity. The flight from Indianapolis to Concord Regional Airport aboard a private jet takes approximately 55 minutes. From there, the driver will swiftly board a helicopter to Charlotte Motor Speedway, and land in the infield. Upon arriving at the Coca-Cola 600, the driver is escorted to his machine, in time for the start, if all goes as planned.

The schedule and the logistics are planned well in advance, and even the slightest deviation can cause significant delay and force the driver to miss the second race. Weather can cause unexpected delay, and even force the effort to be aborted. Due to the complex nature of the scheduling, it is standard practice for the driver's respective teams to have back-up relief drivers standing by at both events, in case the schedule is compromised.

Depending upon which of the two events is considered the top priority, a "drop dead" departure time may be assigned at Indy. According to NASCAR rules, the driver who starts the race in the car receives full championship points for that entry. If the driver is a full-time competitor on the Sprint Cup Series circuit (and only part-time in IndyCar), the team may require the driver to leave Indy before that race is over in order to arrive at Charlotte on-time and receive full points. Conversely, if the Indy 500 is the top priority, and that race is running long, the driver may chose to forgo or delay the trip to Charlotte, and assign the back-up driver to start the 600 instead.

In 2001, Tony Stewart's "Double Duty" effort had the following published itinerary:

"Cross-over" history (1960–1993)

Indianapolis Motor Speedway

The Indianapolis 500 debuted in 1911, and from its onset, was scheduled in conjunction with Memorial Day. In 1960, Charlotte Motor Speedway was completed, and the inaugural World 600 was scheduled for Memorial Day weekend as well. However, for 1960, it was postponed until June 19 in order to ready the facility.

Starting in 1961, both Indy and Charlotte were scheduled around Memorial Day. Through the 1960s, the Indy 500 was normally scheduled for Memorial Day proper (May 30) regardless of the day of the week. When May 30 fell on a Sunday, the Indy 500 was moved to Monday May 31. At Charlotte, the World 600 was to be scheduled for the Sunday closest to Memorial Day. Thus for more than a decade, the two races were actually held on different days of the week. This prompted a handful of NASCAR regulars to attempt to race in the Indy 500. On a few occasions, drivers were able to "cross-over" and compete in both events, or skip the race at Charlotte in favor of Indy.

It should be noted that the NASCAR points system utilized at the time, as well as the structure of the schedule itself, differed substantially from modern times. The system was much more forgiving of drivers who missed a single race, which is why some drivers chose to skip Charlotte altogether.

In 1971, the Uniform Monday Holiday Act took effect, and began to alter the respective schedules for the races. Starting in 1974, the Indy 500 was permanently moved to the Sunday of Memorial Day weekend. Thus from 1974-1992, the races were scheduled for the same day, and at roughly the same starting time. Therefore, drivers were not able to compete in both events. Furthermore, in 1975, the NASCAR points system was overhauled, and became much more unforgiving to drivers missing individual races. Very few NASCAR regulars would chose to skip Charlotte, which was emerging as one of the crown jewels on the Winston Cup calendar.

Starting in 1985, the World 600 secured the sponsorship of The Coca-Cola Company, and henceforth became known as the Coca-Cola 600.

1963

NASCAR regular Junior Johnson entered at Indy, but did not qualify. Curtis Turner passed a rookie test,[4] but later crashed in practice.

1965

The World 600 is held on Sunday May 23,[5] and the Indy 500 is held on Monday May 31. The NASCAR Wood Brothers pit crew were invited to Indy to service the Lotus-Ford entries of Jim Clark and Bobby Johns.[6][7][8][9] Bobby Johns was a NASCAR semi-regular, and he skipped Charlotte to concentrate on Indy.

1966

NASCAR driver Cale Yarborough skips Charlotte and races at Indy. He finishes 28th.[10]

1967

LeeRoy Yarbrough

The World 600 is held on Sunday May 28,[11] and the Indy 500 is scheduled for Tuesday May 30. NASCAR driver LeeRoy Yarbrough skips Charlotte and races at Indy. He finishes 27th,[12] having been involved in three separate spins. Cale Yarborough becomes the first driver to compete in both races in the same year. He dropped out with broken steering and finished 41st at Charlotte. At Indy he placed 17th, spinning out once, and crashing out late in the race.

A rain delay caused the Indy 500 to be held over two days, May 30–31.

1968

The World 600 is held on Sunday May 26,[13] and the Indy 500 is held Thursday May 30. Jerry Grant becomes the second driver to compete in both races in the same year. He finished 12th at Charlotte and 23rd at Indy.[14]

1969

The World 600 is held on Sunday May 25,[15] and the Indy 500 is held Friday May 30. NASCAR driver Lee Roy Yarbrough won the race at Charlotte, and at Indy, he finished 23rd.[16] Charlie Glotzbach, a NASCAR regular, entered at Indy, but failed to qualify.

1970

The World 600 is held on Sunday May 24,[17] and the Indy 500 is held Saturday May 30. NASCAR driver Donnie Allison won the race at Charlotte, and finished 4th at Indy. To date, it is the best combined performance for both races. Lee Roy Yarbrough also competed in both events. He finished 29th at Charlotte and 19th at Indy.

The day after Indy (Sunday May 31), Yarbrough flew to Martinsville to race in the Virginia 500.[18] He dropped out and finished 26th. For the second year in a row, Charlie Glotzbach (who finished 25th at Charlotte) entered, but failed to qualify at Indy.

1971

Cale Yarborough

Memorial Day is moved to Monday, and the Indy 500 is held Saturday May 29. The World 600 is held the very next day, Sunday May 30.[19] NASCAR driver Donnie Allison finished 6th at Indy on Saturday, and finished 2nd at the race at Charlotte. Cale Yarborough skipped Charlotte, and managed to finish 16th at Indy. Sunday night, Donnie Allison flew back to Indianapolis in time to attend the 500 Victory Banquet.[20]

1972

The races are held on successive days again, but no drivers attempt to race in both. Cale Yarborough skipped Charlotte once again, and finish 10th at Indy.

1973

Charlotte is held on Sunday May 27,[21] while Indy is scheduled for Monday May 28. Due to rain, the Indy 500 is not held until Wednesday May 30. Bobby Allison skipped Charlotte and raced at Indy for the first time.

1974

The two events are held on the same day for the first time, with roughly the same start time. No drivers attempt a "cross over."

1975

Bobby Allison skipped Charlotte and raced at Indy. This would be the final time during this era that a noteworthy NASCAR regular did a "cross over" to the Indy 500.

1976

Rookie Janet Guthrie made a highly publicized attempt to qualify at the Indy 500. However, she was not able to get her car up to speed and did not make a qualifying attempt. After creating a media stir, and with the spotlight still on her, she quickly found herself an alternative. Promoter Humpy Wheeler consummated a deal for Guthrie to acquire a car from NASCAR owner Ralph Moody, and within 48 hours, flew her to Charlotte to qualify instead for the World 600.[22] Guthrie started 27th and finished 15th. It was her first NASCAR Winston Cup Series start.

1979

NASCAR regular Neil Bonnett entered at Indy looking to qualify. He was up to speed, however, he suffered a blown engine on the morning of pole qualifying. The following weekend, rain complicated his schedule, and he decided to withdraw from Indy.

1980

Future NASCAR star Tim Richmond, who started his professional driving career in Indy cars, won the Rookie of the Year Award at Indianapolis.

1983

Future NASCAR driver Ken Schrader entered at Indy. He crashed during practice and failed to qualify.

Double Duty history (1994–2014)

Night racing was introduced at Charlotte Motor Speedway starting in 1992.

In 1992, MUSCO Lighting Company installed lights at Charlotte Motor Speedway, becoming the first "speedway" to allow for night racing. For 1992, The Winston was held under-the-lights, but the Coca-Cola 600 was still held during the afternoon. In 1993, the start time for the Coca-Cola 600 was moved to 4:30 p.m. eastern, which eliminated overlap with the Indy 500, and the race became an evening/night race. The 4:30 p.m. start time did not yet allow adequate time for a competitor to compete both, but the idea was planted, and subsequent years, the start time for the 600 was moved later, and a travel window would open up.

1994

IndyCar veteran John Andretti switched full-time to the NASCAR Winston Cup Series starting in 1994, but desired to also compete in the Indy 500. Andretti announced that he would become the first driver ever to attempt to drive in both the Indy 500 and Coca-Cola 600 in the same day. Andretti successfully qualified for both events, and planned a detailed travel itinerary. On race day, Andretti got off to a good start early on. He was running as high as third at Indianapolis during the first half of the race. At the checkered flag, Andretti finished 10th at Indy. He then immediately boarded a helicopter to the airport. He flew to Charlotte, and arrived in just enough time to make the start for the Coca-Cola 600. Since Andretti missed the pre-race drivers' meeting, he was forced to start at the back of the field at Charlotte. He dropped out on lap 220 with engine failure, and finished 36th.

Later in the year, Andretti raced in the Inaugural Brickyard 400. Indy 500 veterans Danny Sullivan, A. J. Foyt, and Geoff Brabham also qualified for the event. But Andretti became the first driver to compete in both events in the same season.

1995

IndyCar veteran Davy Jones announced plans to attempt the "Double Duty." He qualified at Indy, but failed to qualify at Charlotte.

1996

No drivers or teams expressed interest in attempting the double in 1996. Meanwhile, the open wheel "split" was the focus of the month at Indy.

1997

Robby Gordon has attempted "Double Duty" five times.

IndyCar veteran Robby Gordon switched full-time to NASCAR for 1997. Driving for the Felix Sabates SABCO Racing team, he was entered in both races, a highly funded, and highly publicized effort. On race day, however, the Indy 500 was rained out, and the opportunity for the true "Double Duty" was eliminated. Gordon departed the grounds, and went directly to Charlotte when the postponement was announced. Gordon finished 41st at Charlotte after a crash. On Monday, Gordon flew back to Indy, and started the race. The race was halted on lap 15 due to rain, and the conclusion was pushed into Tuesday. On Tuesday, Gordon dropped out early with a fire, and finished 29th.

1998

No drivers attempted the "Double Duty," but one crew member worked both races. Dale Earnhardt's gasman Danny "Chocolate" Myers was invited to also serve as the fueler for Billy Boat's car at A.J. Foyt Racing.[23]

1999

Tony Stewart, an IRL regular from 1996-1998, switched to the NASCAR Winston Cup Series for 1999. He arranged to attempt "Double Duty" for the first time. On pole day, Stewart had to qualify at Indy, then quickly fly to Charlotte in order to participate in the Winston Open. He was forced to take a slow speed in time trials, and ended up qualifying 24th at Indy. That evening, Stewart won the Winston Open, and finished second in main event, The Winston. On race day, Stewart finished 9th at the Indy 500, and was not a factor. At Charlotte, Stewart led laps, and finished 4th.

Robby Gordon and Roberto Moreno became the first two drivers to compete in a CART event and at the Indianapolis 500 on consecutive days. The Motorola 300 at Gateway was held on Saturday May 29. Moreno finished 4th, and Gordon crashed and finished 27th. Gordon and Moreno both returned to Indy in time for Sunday's race.

2000

Robby Gordon attempted "Double Duty" for the second time.[24] On race day, rain delayed the start of the Indy 500 by three hours. Gordon remained at Indianapolis, and started the race as planned. He finished 6th, and back-up driver P. J. Jones started his car at Charlotte instead. After the Indy 500 was over, Gordon flew to Charlotte, and during a pit stop, took over the car from Jones. He drove the car to a 35th place finish.

Three other drivers competed in multiple events during the weekend. Juan Pablo Montoya and Jimmy Vasser participated in the CART Bosch Spark Plug Grand Prix at Nazareth Speedway on Saturday, the day before the Indy 500. Montoya finished 4th, and Vasser 7th. Also on Saturday, Jason Leffler traveled to Charlotte to participate in the NASCAR Busch Series Carquest Auto Parts 300. Leffler finished 21st at Charlotte. All three were back to Indy on Sunday.

2001

Tony Stewart completed all 1,100 miles in 2001.

For the second time, Tony Stewart decided to attempt "Double Duty." Still part of Joe Gibbs Racing in NASCAR, he signed with Chip Ganassi Racing for Indy. On race day, Stewart was a factor all day, leading 13 laps. Despite a brief rain shower, the race did not have a significant delay. Stewart wound up finishing 6th at Indy, on the lead lap. He immediately departed for Charlotte, and made it to the track in just enough time. Starting last due to missing the drivers' meeting, Stewart spun out on lap 2, but claimed it was not due to fatigue. As the race continued, Stewart climbed up the standings, and finished third, on the lead lap. He became the first, and to date, only driver to complete all 1,100 miles of both races in the same day.[25]

2002

Robby Gordon attempted "Double Duty" for the third time, and for the first time, rain did not interfere with his effort. At Indy, he finished 8th on the lead lap. At Charlotte, he started last (due to missing the drivers' meeting), but worked his way up to the top five. He started suffering from handling problems, and cramps in his leg, and he fell two laps down. He made up one lap, and finished 16th. At the end of the day, he was one lap short of completing the entire 1,100 miles.[26]

2003

Robby Gordon attempted "Double Duty" for the fourth time. He qualified on the front row at Indy, but dropped out with gearbox trouble (22nd place). At Charlotte, Gordon was running 17th when the race was called for rain on lap 276 of 400 (414 miles). A week after race day, ESPN aired a one-hour documentary profiling the effort.

2004

For the third year in a row and fifth time overall, Robby Gordon attempted "Double Duty." On race day, rain delayed the start of the Indy 500 by two hours. Gordon started the race as planned. On lap 27, the red flag came out for rain, and the race was halted. It appeared that the rest of the day would likely be a washout, so Gordon departed for Charlotte. After another two hours, the track dried, and the race resumed. Jaques Lazier was standing by, and climbed in Gordon's car to drive relief. He worked his way up the standings, but dropped out on lap 88 with a broken axle. Meanwhile at Charlotte, Robby Gordon finished 20th, three laps down.

On Bump Day (May 23), Tony Stewart created a stir when he made an unexpected visit to the Speedway. After finishing third the previous night in the NEXTEL All-Star Challenge, Stewart was seen in the Foyt garages climbing into a car and at one point even donned a driver's suit. The car was wheeled to the pits and it appeared Stewart was preparing to take practice laps. Members of the media converged, and rumors began buzzing around the track about a possible "Double Duty" attempt. Stewart awaited permission from his sponsors to drive the car, but no deal could be arranged. A. J. Foyt and Stewart were given the dubious "Jigger Award" for pumping life into an otherwise uneventful day.

2005–2010

In 2005, the start time for the Indy 500 was moved to 12 p.m. EST (1 p.m. EDT), which significantly reduced the amount of time available for travel between the events. From 2005-2010, the time frame was deemed insufficient,[27] and despite various rumors of possible attempts over the years, the opportunity to perform "Double Duty" was effectively on hiatus.

2011–2012

For 2011, the start time for the Indy 500 was moved back to 12 noon EDT,[28] which effectively re-opened the travel window and made it possible to attempt "Double Duty" once again. Rumors began to surface that drivers (namely Robby Gordon) were interested in making the attempt. NASCAR regulars Jimmie Johnson and Kasey Kahne also reportedly expressed interest, and a rumor of a $20 million award for winning both races circulated.[29] No plans ever materialized. A year later, despite some rumors about possibly doing the double in 2012, Danica Patrick also nixed plans to compete in both races.[30]

2013

Kurt Busch

In early May 2013, 2004 NASCAR Nextel Cup Series champion Kurt Busch tested for Andretti Autosport at Indianapolis, opening up the possibility of a "Double Duty" attempt in 2014.[31] During the private test, Busch reached a top lap of 218 mph.[32] Busch successfully passed his initial rookie test for the Indianapolis 500.

2014

On March 4, 2014, it was announced that Kurt Busch would attempt "Double Duty" with Andretti Autosport.[33] The effort was done in-part to help raise awareness for military veterans with PTSD and TBI.[34] Busch took part in a refresher test on April 29,[35] and a week later participated in the annual Rookie Orientation Program.[36] Busch led the speed chart on Rookie Orientation day, then posted the second-fastest speed on May 13.

On May 17, the first day of time trials, Busch made two qualifying attempts, and posted the 10th-fastest speed, just missing the Fast Nine Shootout. Just moments after his second attempt, he boarded a helicopter and then flew to Charlotte to compete in the NASCAR Sprint All-Star Race. Busch finished 11th in the All-Star Race, the flew back to Indianapolis for the second day of time trials. On May 18, Busch qualified for the 12th starting position for the Indy 500. The next day, Busch participated in the post-qualifying practice session at Indy. About an hour and a half into the session, he suffered a hard crash in the exit of turn two. He was uninjured but forced to switch to a backup car for Carb Day and race day.

On race day at Indianapolis, Busch started 12th, and fell back to as low as 20th. Although he was not a factor for the win, he finished on the lead lap in 6th and was the highest-finishing rookie. He tied with Robby Gordon and Tony Stewart as the three drivers to finish 6th, the best Indianapolis finish for Double Duty drivers. Busch arrived in Charlotte with time to spare, but was still required to start at the rear of the field due to missing the mandatory pre-race driver's meeting. He ran as high as the top 15, but ultimately failed to finish with a mid-race engine failure. He completed a total of 906 miles (1,458 km) of racing. Busch's effort was documented on the NBCSN series 36.

Race results

The Indianapolis 500 is scheduled for 200 laps (500 miles). The Coca-Cola 600 is scheduled for 400 laps (600 miles). The typical number of starters, respectively, for each race is 33 (Indianapolis) and 43 (Charlotte). During this period, the only deviation was in 1997, when the Indianapolis 500 had 35 starters due to extenuating circumstances following the close of time trials.

Other uses of the term

Indianapolis 500 and Grand Prix of Monaco

During the 1960s and 1970s, a handful of drivers raced at the Indianapolis 500 while maintaining a full-time schedule in Formula One. This would require them to travel between Indianapolis and Europe during the month of May, usually between Indy and the Monaco Grand Prix at Monte Carlo.

Same weekend races

There are other lesser, informal uses of the term "Double Duty" in context to motorsports. Namely instances where a driver competes in two major races on the same day or on successive days. This occurs in a fairly regular fashion in NASCAR, where a driver (often numerous drivers) compete in the Nationwide Series and Sprint Cup Series events, or even Camping World Truck Series races. However, in most cases, the multiple events take place at the same venue, diminishing the complexity of the feat. At times, some drivers even raced the entire Sprint Cup and entire Nationwide schedule, which included some travel between cities for a handful of weekends where the two series were at different venues.

On rare occasions, there have been situations in which a Nationwide Series race became rained out, and was re-scheduled for the day of the Sprint Cup race. This occurred the weekend of the 2007 Winn-Dixie 250 and Pepsi 400 at Daytona, and the 2010 spring weekend at Talladega, with the Aaron's 312 happening after the Aaron's 499. In the later case, the resulting distance was over 851 miles distance traveled, as both races were extended by green-white-checkered finishes.

Similarly, double duty has occurred in instances where a NASCAR driver also takes part in a support race (namely Grand Am), but seldom attempted when the races were at different tracks. This is more prevalent at road courses such as Watkins Glen or Sonoma. Another example of this is at Daytona, where the Paul Revere 250 was held the same day as the Firecracker 400 numerous times, and several drivers competed in both.

Another short-lived "double duty" occurred between the Indianapolis 500 and IMSA. A few drivers, Geoff Brabham, Kevin Cogan, and Rocky Moran, competed at Indy on Sunday, and at Lime Rock on Monday.
