Running track

I used to be a quick walker but never a runner. The carpark at the stadium was taken over by Covid testing people. We have not been able to work out the system for when they are there, the only constant is the time, mid after-noon, and personnel are not happy when folk walk through - even though not near, we keep to extreme edge. People in high viz jackets think they rule! (this is not a rant, pure observation)
