Ask HN: What has happened to C-19 Daily Exercise?

In the UK the lockdown was introduced with an allowance for daily exercise. I was one of the many that took up daily exercise. However, over time, I have noticed there are now not as many people sharing the countryside route I go on. A couple of months ago there were ten times as many people including joggers and dog walkers that should have a high commitment level.

I only have the anecdotal story to tell, does anyone have data or their own anecdotal information to share regarding daily exercise during the lockdown?
