Mr Gnome relishes few things more than a refreshing, protracted dip in water, salty or fresh - he cares not.
I, too, love swimming - though am by no means a strong or particularly proficient breaster of the billows.
A few years back I took part in swimming holiday in the Greek Cyclades organised by Swimtrek.
Well supervised, and in graded ability groups, we swam several crossings between islands, all of which are enchantingly beautiful.
It was definitely the most challenging physical activity in which I have ever taken part - exciting and very rewarding.
No pressure to do more than one felt comfortable with - and I pooped out of the massive six-km crossing that was the biggest swim of the week.
Shortly afterwards I took part in a home-based Swimtrek adventure - a summer day out swimming a stretch of the Thames from Gloucestershire into Oxfordshire. Writer Kate Rew wrote it up for The Observer.
The piece also appears on page 94 of her glamorous book Wild Swim.
Now, where did I leave my goggles?
