Notes
Well that hurt more than it should have. And it hurt in my legs. My lungs were fine; the rest of me actually wanted to keep going, but my legs wouldn't move anymore. Stranger: it is the next day and my legs aren't sore at all. Guess the endurance in my leg muscles needs some work!
It was also windy, very cold, and pretty miserable. So my shoulders kept tensing up to brace against the cold and the wind. I am sure that didn't help with energy levels at all.
