I drank plenty of water on this ride; I'm convinced I just didn't eat right. It's not the amount, but what was/wasn't eaten. No where near enough carbs here. Even if I'd grabbed some granola bars or even a donut or 2 would have made a lot of difference. Sometimes it's just a mind thing too. I had 20 mph cross winds for most of this and near 90 degrees. Again, the mind does things to you too.
Nope, it had to be the food!
