It's fun to say "Bonk!", but it's no fun to do it

Yesterday, I had a group training run over 6 really hilly miles. Because I injured myself attempting to ski and had an awful week of training, I knew that I wouldn't be adequately prepared. The distance itself wasn't so much a concern as the hills, and the fact that I need very consistent training momentum in order to pull off what for me is a long run.

I got as much sleep as possible the night before, avoided sugar, and had what I felt was a pretty adequate breakfast well ahead of the run. So what did I do? Bonk. Tap out. Crash. Walk. Walk alot.
