I've been off for a few days. That little nag in my calf sort of crept up the back of my leg and turned in to a big bad hamstring strain. Yeouch. The bike ride didn't hurt a bit today, so that's good news. I wanted to do 15 miles, but lost the bike trail in an unfamiliar neighborhood, so turned around just after 6 or so and headed home.
Nutrition note - I took a Larabar with me on my ride today. I had a couple of bite on the way out, and finished it up after I turned around. Had no problems with my tummy, but wished for a little more water. Eating while cycling sure is different than while running!
