Wow, was not really aware of this! Have always believed "by the time you're thirsty, it's too late." Maybe not. That large corporations would promote junk science to protect their profit centers is certainly no surprise.

"Bottom line: drinking ahead of thirst:

General public—Drinking ahead of thirst may worsen performance in endurance exercise and carries a rare but serious risk of hyponatraemia. The body’s internal mechanism for staying hydrated is cheaper, easier, and seems to be the best way to optimise performance

Professional athletes—Elite endurance athletes perform best when they drink to thirst; some studies suggest exercise induced dehydration can improve performance"

Here's the link to the suite of "Start of the Olympics" exercise/sports drink/hydration articles released by the eminent British Journal of Medicine. The others can be accessed by clicking on the "related content" tab. Only one has a pay wall.

I can speak a bit about endurance athlete performance and drinking.....the problem is not drinking before you are thirsty, the problem is drinking too much. Most endurance athletes know their body very well and can regulate water intake as needed. People not used to stressing their bodies beyond what is considered normal may not recognize when water is needed or when they have had too much to drink and/or have created an imbalance in their electrolytes and fluids. Over drinking can be as problematic as not drinking enough.
