Driver documents fluids taken and weight lost at Indianapolis Landon Cassill performed a "science experiment" during Sunday's Crown Royal presents the Jeff Kyle 400 at the Brickyard at Indianapolis Motor Speedway. The full-time driver in both the Sprint Cup and XFINITY Series proved his stamina after May's Coca-Cola 600 , running 14 miles to the NASCAR Hall of Fame following NASCAR's longest race of the season. He also qualified to compete in next month's Ironman 70.3 World Championship in Austria. As he braved temperatures that saw one in-car thermometer in Casey Mears ' car reach at least 131 degrees, Cassill had a query: How much weight would a driver lose over 400 miles in a race? See the results of his experiment below. Science experiment!

RELATED: Photos of Stewart through the years " Bowyer tabbed as replacement Three-time premier series champion Tony Stewart smiled and conceded it was a "formality at this point" in announcing Wednesday afternoon that he would step away from full-time NASCAR Sprint Cup Series competition following the 2016 season. "It was a choice that is 100 percent mine, no pressure from anybody," Stewart said of his decision not to compete full-time anymore. "If anything, it's been the opposite, more people trying to talk me out of it. "Everyone in their career makes a decision when it's time for a change. I think deep down you know when it's time to do something different and make a change like this." Appearing jovial and without a hint of second-thought about his career decision, Stewart joked he was bringing Harry Gant out of retirement to drive the the Stewart-Haas Racing No. 14 Chevy in 2017, then confirmed that actually Clint Bowyer would be taking over his seat. The news confirmed months of speculation and rumor about Stewart's future and solidified Bowyer's career path as well with Bowyer's Michael Waltrip Racing team closing operations at the end of 2015. "It's all about people, all about culture for me, and I don't think the fit factor could be any better," said Bowyer, acknowledging the SHR ride was "one of the biggest powerhouses in the sport" and said an announcement is coming later this week about his 2016 plans. Wednesday was clearly more about "the people's champion" as Stewart is often referred. One of the most popular and accomplished champions to ever compete in NASCAR's marquee series, Stewart, 44, has won three premier series titles as a driver (2002, 2005, 2011) and two as an owner (2011, 2014), accumulated 48 victories and won over countless hearts as a kind of extreme throw-back talent garnering comparisons to racing's all-time greats such as A.J. Foyt and Dale Earnhardt. Quite simply, Stewart won in every car he drove. And NASCAR fans always appreciated that about the driver known by his nickname, "Smoke." RELATED: Drivers react to Stewart's announcement Stewart won a NASCAR Sprint Cup Series race in 15 straight seasons from his 1999 rookie year through 2013, and he has 11 NASCAR XFINITY Series wins in 94 starts -- roughly winning once every 10 times he tried. He won twice in six NASCAR Camping World Truck Series starts and had five top-10 finishes. "When I think of Tony Stewart , unmatched passion and a pure love of the sport come to mind," NASCAR Chairman and CEO Brian France said in a release. "He has won championships and millions of fans. But he has given back so much more, and that's what I admire most. Today's news was bittersweet for all, but we know Tony will continue to be a big part of our sport in his roles as a team and track owner. On behalf of the entire NASCAR family, I thank Tony for his many years of excellence and competitiveness, and wish him nothing but the best in his final season as a driver in the Sprint Cup Series." The 1997 IndyCar champion -- and 1996 Indy 500 Rookie of the Race -- proved his mettle against motorsports' best drivers, winning four times in IROC competition, earning the 2006 IROC championship and finishing runner-up in 2001. In 1999 he completed racing's Memorial Day "Double," finishing ninth in the Indianapolis 500 and fourth in NASCAR's Coca-Cola 600 later that same day in North Carolina. Stewart was the first driver in history to win all three major United States Auto Club national championships -- Midget, Sprint and Silver Crown -- in a single season. So after essentially four decades behind the wheel fulltime, Stewart said he contemplated this decision for a while and said this week, he is completely at peace. "I've learned a lot about myself," Stewart said. You run through the range of emotions. There's days you're like, I can't wait, and then there's days that are like, man, do I ‑‑ you battle back and forth. "I'm not leaving the sport I love. I'm not walking away from something I'm passionate about, I'm just changing roles, which it's like just moving to a different position in a company. "I'm not really retiring, I'm just changing positions." RELATED: Best quotes from Stewart's press conference It's been an admittedly uphill climb for the champ after the last three seasons of horrible injury and extreme heartbreak. He missed the last 15 races in the 2013 season after suffering a compound leg fracture while competing in a sprint car race. Then last year, while still mending from that injury, Stewart was involved in another sprint car accident. This time, another competitor, Kevin Ward Jr., was killed when, after approaching Stewart's car on track during a caution period, the car struck Ward. Stewart sat out three Sprint Cup races immediately after. No criminal charges were found to be justified against Stewart; the Ward family filed a civil lawsuit against him a year later. On Wednesday Stewart stressed that his decision to stop driving in the Cup series full-time had "zero percent to with (the Ward situation)" and that physically, "my leg feels fine, there's nothing wrong with my leg." He said he may even compete in Sprint cars again. He listed the Rolex 24 at Daytona as a possibility and mentioned racing modifieds and making sporadic starts in the XFINITY and Camping World Truck Series -- all things he plans to do without the stress and full schedule of racing full-time in the Sprint Cup ranks. RELATED: Tony talks toll on leg, life In the past two seasons, Stewart has struggled to post the kind of top-shelf results both he and his fans had grown accustomed to seeing. But he has consistently insisted that was more to do with the current rules package than his off-track distractions. He said earlier this year that NASCAR's new high downforce, low horsepower car does not suit his style and is actually "the opposite of everything I've ever driven. "It's like I'm in the middle of a calculus equation and I didn't take pre-calculus,'' Stewart told NASCAR.com this May. He is currently 25th in the Sprint Cup Series driver standings with a sub-standard two top-10 finishes in his No. 14 Bass Pro Shops/Mobil 1 Chevrolet this year. But he was adamant that he would not be coasting in his final season and that this decision was not "performance based." Stepping away from his NASCAR driving duties, Stewart's focus shifts to running his beloved Eldora Speedway in Ohio and to being a team owner. His resume out of the car is already as impressive as his work behind the steering wheel. "It's just time to do what we're doing," Stewart said. "I still fully anticipate we're going to get things turned around. If I didn't feel that way, I wouldn't waste my time next year for anybody. I'm not a guy that's going to get in a car and ride. We're full steam ahead. "We're going to keep working and try to win as many races as we can next year, and that goal is going to be ‑‑ when you guys get to February, go ahead and write this down, what our goals are for the year, we're going to try to win races, try to win the Daytona 500 , then the Brickyard 400 , the Southern 500, and try to win a championship." Ultimately, stepping away from his NASCAR driving duties, Stewart's focus shifts to running his beloved Eldora Speedway in Ohio and to being a team owner. His effort out of the car is already as impressive as his work behind the steering wheel. His namesake Stewart-Haas Racing No. 4 team is the reigning Sprint Cup owner champion thanks to Kevin Harvick 's 2014 championship run, and two of his team's four drivers -- Harvick and Kurt Busch -- are in this year's Chase for the NASCAR Sprint Cup . This summer Stewart collected his 10th Knoxville Nationals trophy in the World of Outlaws Sprint Car Series fielding a car for driver Donny Schatz, who has also delivered five World of Outlaw championships for Stewart. He has 23 national titles as a team owner. "I've won more car championships as an owner than a driver," Stewart said "I'm definitely as competitive as an owner as I am a driver. …That fire's still there and that's what makes this transition easier." While his success driving and fielding cars is partly responsible for Stewart's incredible popularity over the years, he is also one of the sport's most robust personalities. RELATED: 'Smoke' still the people's champion He's not afraid to express his displeasure at his competitors' blunders, and the other drivers have come to expect either face time or bumper time with him after on track run-ins. And Stewart's "no-fools" tolerance policy extends to the media covering his career. There are highlight reels devoted to showcasing him sparring with reporters in press conferences and on pit road -- his wit and sarcasm legendary with the media corps. He grinned broadly and warned the room of reporters on Wednesday that he will not follow the guide of four-time champ Jeff Gordon who has met with the press nearly every week during this -- his last -- year of NASCAR competition. "Let's establish this right now: I will not be coming to the media center every week to talk about it,'" Stewart said smiling and shaking his head. "You can save your gifts. I've got enough rocking chairs at home as it is. I bought those when I wanted to go sit on my own rocking chair. You don't have to give me one. "I'm content to go race and be around the racing community and the racing family and be around our fans," he continued. "They can just send me a note from the track president and say, hey, thank you, and that'll be sufficient for me. "I think it's been very fitting for Jeff [Gordon]. I don't think I'm worthy of that kind of admiration because I think Jeff has really done so much for the sport that nobody will ever be able to do again. I think that kind of celebration is reserved for somebody like Jeff." One thing Stewart has across the board is respect -- from his competitors, to the fans and to the media who will be watching closely to see how this next chapter in his career and life plays out. He gave a couple hints on Wednesday afternoon. When it's time to drop the green flag for the 2017 Daytona 500 – the first one run without Tony Stewart on the grid since 1999 – the champ says he hasn't figured out quite yet where he'll be, but spoke about one possibility. "I'll probably be on some fan's motor home on the back stretch promoting our sponsors," Stewart said laughing. "I have no idea where I'm supposed to be yet. I've got a whole year to figure that out."
