Running update

This injury sucks.
I only ran 10 km today. My physiotherapist says not to run for more than an hour, so I’m good there. But what bothers me is that the group I would normally run with is doing 29km right now. I started with them and they should be just about reaching the halfway point as I type this. I ran with them for 5km, keeping up well, but it fell apart as I turned around. Going down the hill things really started hurting and I had to walk large chunks of the route back.
Physical exercise: You spend so much effort to bring yourself up to a certain level, and it is so easily taken away. And this is the third Spring in a row that I’ve been injured. Two years ago it was the knee. Last year the foot. This is the season of the shoulder.
