My normal pace/time for a round of golf is between 2.5 to 3 hours.
If it was taking over 5 hours to play I would probably want to take my lunch with me.
Snelly is nearly spot on with his rant. I think you do need some water on a warm day, and drink before you feel thirsty.
As for the rest it is just general rubbish made up by guys trying to sell a product [sports drinks] or trying to make a living by lecturing to the soft headed.
Just about sums it up for me
