One of MY best friends in the world ran 1:01 for was half and 2:12 in the marathon, and drank about 2-4 liters of Coca-Cola every day during training. He "carbo-loaded" on fries, gummi bears, white bread with Nutella and washed it all down with Coca-Cola. Had to be Coca-cola, not Pepsi.
When he ran 2:12 at Amsterdam in 2003, his dinner the night before the race was a McDonalds BigMac, Large Fries, a pile of Haribo gummi worms and 2 liters of Coca-cola. I am not making this up. He had to eat coca-cola and junk food in order to run fast.
He always said "I don't drink water because fish like to pee in it!"
Also he never ate any vegetables or anything green, except for green gummi candy.
In April 2007, I was in Belgium the weekend after I ran the Paris marathon, and he was getting ready for the Antwerp marathon. The night before the race, I took him to a pasta place, thinking that some "healthy" food would help him. He ate a plate of spaghetti with meat sauce, but his body rejected it, and he ended up pulling a "Radcliffe," and crapping on the road about 13km into the marathon, live on Belgian national TV.
