Devil's bridge at dusk

It is just light enough in the early evenings now that an after work run is not out of the question (as long as I'm working from home and can get out of the door shortly after five).

I've been running for about twenty-six years, I reckon, and, mercifully, that's been injury free. Just recently, though, I've had some minor knee related concerns. It was while I was out running this evening that I remembered this has happened before; it's whenever I routinely use my 'ergonomic kneeling chair', which I reckon puts a little more stress on my knees.

But I like the chair and my knees are all right and I had a good run, so I'll stick with it.
