Thirst as a Signal for Fluid Intake
"As to the taking of stimulants during the race, I will say that I know from actual experience that the full [marathon] race can be covered in creditable time without so much as a single drop of water being taken or even sponging of the head—I have done it myself. This of course is when in perfect trim."

Making sense of why runners collapse
Why would anyone expect the symptom of thirst to be present in collapsed runners? Thirst is such a powerful urge that any thirsty marathon runner suffering from dehydration during a race will simply stop at the next refreshment station and drink until her thirst is slaked. Simple.

Introduction – A change in view of hydration
Marathon runners were not alone in this belief. Cyclists in the race that was considered the ultimate physical challenge—the Tour de France—were advised similarly: “Avoid drinking when racing, especially in hot weather. Drink as little as possible, and with the liquid not too cold. It is only a question of will power.

Waterlogged
The Serious Problem of Overhydration in Endurance Sports
|
Short Description
Tim Noakes, medical doctor, exercise physiologist, and internationally recognized expert on human performance, debunks current hydration beliefs. Waterlogged outlines practices that endurance athletes should follow, variables they should consider, and guidelines they should use to maintain proper fluid balance in sport training and performance.

“Drink as much as you can, even before you feel thirsty." That's been the mantra to athletes and coaches for the past three decades, and bottled water and sports drinks have flourished into billion-dollar industries in the same short time. The problem is that an overhydrated athlete is at a performance disadvantage and at risk of exercise-associated hyponatremia (EAH)--a potentially fatal condition.
Dr. Tim Noakes takes you inside the science of athlete hydration for a fascinating look at the human body’s need for water and how it uses the liquids it ingests. He also chronicles the shaky research that reported findings contrary to results in nearly all of Noakes’ extensive and since-confirmed studies.
In Waterlogged, Noakes sets the record straight, exposing the myths surrounding dehydration and presenting up-to-date hydration guidelines for endurance sport and prolonged training activities. Enough with oversold sports drinks and obsessing over water consumption before, during, and after every workout, he says. Time for the facts—and the prevention of any more needless fatalities.

Appendixes
Known throughout the academic community for the high-caliber nature of his scientific insights and work, Dr. Timothy Noakes is Discovery Health professor of exercise and sport science at the University of Cape Town in South Africa. He is also director of the Medical Research Council/University of Cape Town Research Unit for Exercise Science and Sports Medicine at the Sports Science Institute of South Africa in Newlands. Noakes was awarded a doctorate in science (DSc) in 2002, the highest degree awarded by the University of Cape Town. Publishing the first scientific article on exercise-associated hyponatremia (EAH) is considered among his greatest achievements. Noakes is a veteran of more than 70 marathons and ultramarathons, and his book Lore of Running (Human Kinetics, 2003) is considered a classic by serious distance runners. In addition, Noakes is an editorial board member for many international sport science journals and a former president of the South African Sports Medicine Association. In 1996, he presented the prestigious J.B. Wolffe Memorial Lecture at the American College of Sports Medicine’s annual meeting. In 1999 he was elected as one of 22 founding members of the International Olympic Committee’s Olympic Science Academy. The National Research Foundation of South Africa considers Noakes an A-rated scientist, and in 2008 he received the Order of Mapungubwe (Silver) from the president of South Africa. Noakes and his wife, Marilyn Anne, reside in Cape Town.
"For sport science devotees at all levels, and those who love to just go for a run, Dr. Noakes' book is the ultimate combination of scientific rigor and practical advice. A must on every athlete’s bookshelf."
—Karim Khan, Editor of British Journal of Sports Medicine
"Finally, an unbiased look at fluid replacement: the real science behind thirst, fluid balance, and thermoregulation during exercise! Waterlogged is a must-read for athletes, coaches, parents, and sports medicine professionals."
—Sandra Fowkes Godek, PhD, ATC, HEAT Institute Director West Chester University
