Nascar driver loses 10% of body weight during 400-mile race

One for those who say racing drivers aren't proper athletes

They might just be 'going around in circles' but the rigours of sitting behind the wheel of a stock car for hours travelling at speeds of up to 200mph take their toll on the human body, not least in terms of weight loss. Nascar driver Landon Cassill decided to perform an experiment during yesterday's Brickyard 400 at the Indianapolis Motor Speedway, weighing himself before and after the race, as well as monitoring his fluid intake, to see exactly what the effects of the physical exertion and the sweltering heat would be. The results showed net weight loss of eight pounds, or 3.6kg, but with Cassill taking on 7lbs of fluids during the race the overall figure is closer to 15lbs, or just under 7kg. https://twitter.com/landoncassill/status/625378071449874432 https://twitter.com/landoncassill/status/625442792609681408 https://twitter.com/landoncassill/status/625445903105699842
