Gas stations are lovely places. I took a 60 mile ride in the foothills yesterday. After running low on water and most of my energy being gone I hit a conoco. butterfinger..... yummy
Worked great.

Anyhow, bonking is quite annoying. I have only done this once and could barely move. It took my 90 minutes to ride 5 miles. Never again!
I think I had a partial bonk a few weeks ago. After sprinting home my hands were shaking so much it took me 10 minutes to make a PGJ sandwich. However, that could be something entirely different. *shrugs*

Burn out just takes time to get over. It happens to me from time to time.
