After my walk on Thursday morning everything was fine all day. Then I woke up Friday morning with a sore big toe. I thought I'd research a bit about feet and was amazed (even at my age) to learn that our toes aren't limited to the tiny portions that stick out like little growths at the end of our feet. A large part of the toe is "inside".

Anyway, by Saturday it was fine and I went for my scheduled walk. However, I think I started a bit fast and was concerned I was developing a cramp in my left calf muscle. So, I slowed my pace a bit and was fine. 4km, 42 minutes, 14C, cloudy, slight breeze, same route; next "walk" Tues morning
