I laid down on the cool, shaded concrete in our front yard yesterday morning after a short (for me) run, and in little time created a pretty full silhouette from my cascade of perspiration. Yes, it was hot out there, even though I went earlier than almost ever, expressly to try to beat the heat. Also, because we had appointments to keep, I ran in the neighborhood, which is hillier than I would prefer to be running in.
You can see my meandering route, which took 40-plus minutes and involved 270 feet of vertical change, here. Seemed like a lot, to a slug who prefers flat pavement.
It just occurred to me (honest, just now): That's a semi-slender silhouette! Who is that guy?
