One of London’s best-known events is the annual Boat Race, a contest between crews from Oxford and Cambridge University Boat Clubs held every spring on the River Thames. The two teams go head to head over a 4.2 mile (6.8 kilometre) course that stretches between Putney and Mortlake.

I’m standing in the bathroom on the upper floor – you really don’t have to know what I’m doing –looking wistfully through the chartreuse-coloured cascade that is the weeping willow at the bottom of our garden and across the canal to Victoria Park. It is `just spring when the world is puddle-wonderful’ as American poet E.E. Cummings once put it, and we can no longer enter it. Like pints after work and an evening at the theatre, our beloved park is just a memory. It’s encaged by tall iron gates.
