You open any book about biking and they tell you how to eat. You slurp down some jelly-like concoction with just the right balance of nutrients and minerals that pump your legs for the next 50 miles.
Why bike if you can't eat those sinfully sweet items that you would otherwise have to shun?
I bike for Jack's donuts.
Rich beyond belief, these babies carry enough calories to fuel my hundred mile bike ride. I once was stuck in Indianapolis with no Jacks and aspirations for a day's century. I tried an Indianapolis donut and fizzled at mile 62.
Next, the Jack's donut as a reward for all of my hard work. After that it's pure carbs - easy to digest and full of calories.
A cherry pie, chocolate chip cookies (preferably home-made). On a hot day I need to segue to salty snacks - Chex mix or pretzels.
I did find out, to my amazement, that I not only am allowed to eat a lot when I'm biking, I must eat or I bonk.
Bonk is when your body runs out of fuel and you just stop cold. I have had to lay down on the side of a road more than once to try to recover from a bonk. One time I remember lying down on the cold floor of a gas station 3 miles from my house trying to recuperate enough to limp home the last few miles.
But I eat like I bike...
...for the pure hedonistic joy of it.
