In reply to Misha:
Perhaps I'm being dense or missing something, but the gov's self-isolation page seems to suggest exercise outside is ok as long as you aren't near anyone else:
"If possible, you should not go out even to buy food or other essentials, other than exercise, and in that case at a safe distance from others. "
Which makes sense really... don't do things that put yourself at risk, but you can walk or run without having to go near anyone. Basically be sensible and responsible, especially if you are self-isolating.

I am heartened that the climbing and outdoor community is taking this so seriously and for us the restrictions are likely to mean a lot more change in lifestyle than more sedentary people, but I do wonder whether e.g. DIY enthusiasts are urging each other to stop using power tools, alcohol enthusiasts are stopping drinking, smokers giving up cigarettes, given their potential for injury and illness.... From what I have seen I would suspect not.
