Are Park Runs Destructive ?

[OB1]

Hi OB1 - managed to nick the V60 record at Bunyaville by 4 seconds on Saturday! B2B this weekend.
Well done with your PB at Marple - I've never done the Marple parkrun but used to run round Brabyns on a regular basis as I lived in Marple Bridge around 40 years ago.

Nice effort WH. I had to smile reading your comment about the 2 young whippersnappers.
Look at it this way, they were just providing some LHS balance to counter your RHS leverage on the age-grade chart.
