Spindly legs

My legs have gotten more of a "biker shape" this year than they ever have before. I've been feeling good about that today. On the mountain bike, I felt like they were good and tough. Not tree trunk tough, but tough for what I'm used to seeing. Today I went and did 90 second intervals with Dan up by the Provo temple, and that feeling disappeared. The first half of our interval was maybe a 3% grade, and then a crosswalk, and then it kicked up to, I don't know, maybe 5%. Dan kicked it at the crosswalk every time. He blew me away, and blew my mind. As I struggled to stay within 15 yards of him, I'd look down at my legs, and only one word came to mind. Spindly. (Long and skinny, often denoting weakness). Yeah. Spindly.
