veeeeeeery interesting reads, I am rather impressed by both the distances many of you have covered, and the detail put down on your calorie and whatsit input.
shall ruminate on all of this and try to remember some of this to help my endurance. When I rode long days on tours (long days for me that is) I did learn what foods worked and really just sort of muddled through by seeing what didnt work and what helped.
I had a friend who drove across Canada once, and he was doing 300-350km days, and while he was on a lightly loaded racing bike, the distances did and still do astound me in comparing to my 125km max days (albeit with lots of stuff on the bike)--that said, my friend was and still is a heck of an athlete, whereas I am just a regular old tall and skinny guy.
