When cab drivers want to start work in London they have to prove they have “the knowledge” - an intimate understanding of the city’s streets and locations.

I suspect something similar operates among the posties of Bath. Key information about roads and the secret numbering of houses that can only be passed on to other postmen and women, leaving the rest of us bemused.

On Tuesday I navigated the intricacies of Newton Road and Redland Park and found myself up all sorts of alleys and along trails of disappearing house numbers. It was Bath GoodGym’s mission to deliver flower show leaflets to the area on behalf of the Twerton and Whiteway Community Network.

A hundred of them found their target doormats and will, I hope, inspire the householders to go along to the event on Saturday 14 June, reviving an old tradition and bringing the community together.
