One essential ritual of my school life was the annual Summer school Sports day where like it or not you were entered into the various sporting competitions for your school year group and house (cos we had operated a 'House' system).
There were a number of them that stick in my mind and this is one of them.
The other common race was the Sack Race where you'd stand up wearing a sack over your PE kit holding the edges and have to run with the itchy material not tripping up over yourself which usually happened.
Usually some teacher or helper had the first aid kit at hand!
Although I was rubbish at it, I enjoyed taking part although we'd have to walk to the local park where it was held and was the 'Mascot' for our House.
