I eat 3 Powerbars a week, one before each run. I've been doing this regimen for years. I've probably eaten 750 powerbars.
Mostly I eat the Chocolate flavor, but I've tried them all. It doesn't really matter what labeled flavor is. They all basically taste like ass with sugar. Cookies 'n' Ass, Chocolate Peanut Ass, Cinnamon Apple Ass, Ass 'n' Ass, whatever. I don't eat them because I love the taste (of ass), I eat them because they're supposed to be a pretty good source of fuel for running.
But the running is good, right, Mike? You enjoy the running?
Oh, god, no. Eating the chocolately assy Powerbar is probably the best part of my runs. A friend asked the other day what I think about when I'm running. My answer was basically this, "I mostly spend the whole time contemplating how much I'm hating that particular instant, how tired I am, how hot I am, how pained, or how just plain weary. I distract myself about every 30 seconds by looking at my watch to see how many seconds I have left. I might look at my watch 100 times on a long run. I hate every moment of most runs."
She looked at me like I was an idiot. She suggested that I take up biking, or hiking, or any other form of exercise. I shrugged off all her ideas.
I'm going to run until I can't run any more. It's going pretty well.
