The old guys who sometimes visit here run for miles. But they have the advantage of a suitable climate. Where I live, runners tend to melt. Nevertheless, yesterday morning after the usual walk, when I could be sure all the old injuries had fully warmed up, I ran once round the park. Four minutes or so. Pathetic, but there was no damage, so I'll do it again.
When I run there are usually several useful side effects, some of them printable. For one thing, for the rest of the day the appetite soars. Yesterday, five o'clock nibbles went on for so long, I had to open a second bottle of beer! If I can just run a couple of times a week and avoid injury, I'll end up eating enough to achieve fat bastardhood.
On holiday recently, I did lots of walking, which is good but not as good as running. In the photo, you can just see the cellmate disappearing over the horizon in an attempt to avoid being in the shot.
