Are Park Runs Destructive ?

[OB1]

Most parkruns in Oz are on road and many of them are on concrete which I don't find very forgiving. But we have found one in North Brusbane which is off road and hilly - are there any comparable parkruns in the UK?

Lyme Park is trail and quite hilly for a Parkrun.
Not done it yet mind, but it is on my shortlist for autumn.
