How much (and what type) of carbo load did you do pre-race and day before?
How much heed are you putting on that bottle?
How many oz are on that bottle?
How much faster were you doing those laps then your normal "fast" pace?
I personally don't 'overplan', but I eat a very balanced diet most of the time, so I mostly just eat more breads for a few days prior to any event. I also eat a few more sweets.
On race day, I try and eat light, but with a bunch of calories in the morning. I had a buttered bagel and banana. In between laps, I had a gel, and a powerbar. I also took two electrolite pills in between laps, and drank lots of water.
I personally don't usually use anything but water while riding. I would rather get my calories with soft foods. PB and J etc.... Water is the best thing....IMPO.
It is hard to say how much harder I rode this race, but I can say that I was not letting up, even when it hurt...
Maybe I am not the model, and I rode a totally different race than you. 3 or 4 sprint laps is very different than just pedalling for 6 hours......Personally I would send Marcel a p.m. He learned this stuff through trail and error, but he has got it down as far as endurance races go.
