To what extent is this is possible? This year, the problem I consistently run into is that on more challenging rides is around the 8th hour, I start hating all food and drink formulas -- only plain water tastes good. Trying to force myself just makes me feel sick. I can stand a nibble of fruit or a couple chips, but we're talking snacks that are only about 50 calories.
What I want to do is eat a larger breakfast while I still feel good and consume 100 calories or less per hour on the logic that my body will still be working on breakfast. Will this work?
Just in case I'm already doing something wrong, my normal plan is to consume about 700 calories at breakfast and then 250 calories per hour. Usually, I feel great for the first 6 or 7 hours. Around hour 8, I don't feel as good, and by hour 10, I'm sometimes in a daze. I'll be a little tired, but there's still some strength, so it's not like a bonk. Rather, I just feel sick and my head doesn't work.
I normally carry all my own food. On this last ride, I was hauling 800g of perpetuem, 550g of which I consumed before deciding I was going to ride the last couple hours on water alone (I was carrying an extra 140g because I was originally going to extend the ride if I felt good enough). I realize this sounds horrible, but it actually works better than anything else I've tried yet.
Bottom line is that I'm looking for a better way to stay fed on mountain rides. I want to eat more beforehand, less during, and I'd really like to carry as little food as possible. I'm willing to risk getting sick and not finishing a big ride to do an experiment, but I wanted to see if what I want to do is even vaguely feasible.
Or is it possible my eating plan is fine, but I'm not in good enough shape to do the rides I'm attempting -- i.e. I'm experiencing simple exhaustion? Ever since switching jobs in April, I've only been riding half as much as I used to. I'm no couch potato, but I'm starting to have problems on long rides that I never had before.
