Hello Colin. Firstly I’m not sure how field hockey was determined to begin with I’ll be honest. But it is down to 15 years of local knowledge. I’m more interested how the original sport was determined incorrectly first. Besides local knowledge it would be possible to see on the Schools sport website that the hockey is done on the astroturf pitches and football, rugby, and cricket on others. Cricket can also be seen in the aerial photos for the pavilion fields marked out as well.
