“The idea that thirst comes too late is a marketing ploy of the sports-drink industry," says Tim Noakes, M.D., professor of sport and exercise science at University of Cape Town, South Africa.

Pretty important book here, especially for me as a coach. I just got my copy of Dr. Tim Noakes newest book and it is an eye-opener. I'll let Dr. Noakes summarize his conclusions which in no way should dissuade you from buying a copy of the book for yourself.

from p.353: Summary
In this book I have described my odyssey of three decades that began when I received Eleanor Sadler's letter in June 1981. During this journey I have learned how science is meant to work and conversely how it often does - a quite different reality. This has been a bitter lesson.
     Over this period of 30 years I did, however, learn the real science of hydration:
• Your body will tell you what it needs, if you just listen.
• So drink only ad libitum - that is, according to the dictates of thirst.
• Dehydration is not a disease. Nor does dehydration contribute in any way to any illnesses associated with prolonged exercise like road, marathon, and ultramarathon running races and triathlons.
• If you are carbohydrate adapted, to optimize your performance during more prolonged competitive exercise, you will need to ingest some carbohydrate or perhaps preferably a favorite food.
• There is no need to increase your habitual daily sodium intake above that dictated by your appetite.
• There is no need to ingest additional sodium during exercise.
• Understand that much of what you believe about your personal well-being is the result of targeted manipulations by industries whose principal focus is their commerical fitness and not necessarily your health or safety.
