This is all stuff I have gleaned from my friends, trainer, and what-not. Generally they have told me to fuel consistently throughout a ride, especially the first half of it. Anything taken in in the last 30 minutes of a ride will be for comfort only because it will hit after the ride is over. Ditto on the previous about eating right afterwards. As for the rest of the meal eating.....alot of riders stress eating a lot of food the night and the morning before hard efforts or long ones. I read in a Title 9 news letter that men will metabolize large doses over long periods of time, so carbo loading does work for them. Women will not. We are eat and use immediatly kind of beings. So, eat what you need, and fuel throughout the rides. Any extra calorie intake piles up, so the article said. I took it to heart and lost 5 pounds in just a couple of weeks.
Personally I love salads. I eat three a week for supperOther than that I eat six small meals/snacks throughout the day ranging from 200 to 400 calories a pop. Just my prefs.
Hope it helps.
