Cassill loses eight pounds in Brickyard 400
July 26, 2015, Staff report, NASCAR.com
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! My pre race weight, I'm planning on taking in 80oz of fluids in the race, we'll see what I lose. pic.twitter.com/QJ0W071Yz3— landon cassill (@landoncassill) July 26, 2015
Consumed 110oz fluids & 1100 calories->post race 147.4lbs. That's -15lbs, replaced 7 of it with fluids, net loss 8lbs pic.twitter.com/WsXq6rsvO0— landon cassill (@landoncassill) July 26, 2015
That's a 10% gross loss of body weight, getting it back to 5% with fluid replacement. I think I'd like to see closer to 3%.— landon cassill (@landoncassill) July 26, 2015
