Are we still debating the best hydration practices for hot weather training or have we finally accepted that drinking 8-10 glasses of water a day is an outdated myth with no scientific backing? It seems like every other week, someone is peddling a new hydration product or strategy thats supposed to revolutionize our training, but at the end of the day, were still stuck with the same old questions: how much water should we be drinking, whats the ideal electrolyte balance, and whats the deal with all these fancy new hydration products that claim to do everything short of giving us a competitive edge? Can we get a straight answer for once, or are we doomed to keep repeating the same hydration mistakes over and over again? And while were at it, can someone please explain to me why so many cyclists still insist on drinking plain old water during intense training sessions, despite the overwhelming evidence that its not enough to replenish lost electrolytes and maintain optimal performance?
