I overdid it riding my bike to work this morning. I felt faint and had to lie on the floor for a while in my office before I could start my day.
I only live a mile and a half from work, but over that short distance my route drops about 120 feet in elevation, then climbs back up another 90 feet. Back when I was mountain biking regularly, that would have been nothing. Now that I’m older and out of shape, pushing hard on that climb — even on pavement — is too much.
At least someone brought doughnuts.
