Sunday lie-in or up early? I like a bit of a lie-in. My wife, Shara, and I will argue who’s walking the dogs.
Where do you walk? Down to the jetty, 10 minutes from the lighthouse, so they can go crazy chasing the seagulls, then a power walk back up. I’ll be barefoot, shirt off, to get grounded, whatever the weather.
Where do you live? In a cottage on a little island called Saint Tudwal’s, off the north Welsh coast, off grid with a wind turbine and solar panels. No, you can’t order a Deliveroo, but there’s very good pizza place on the mainland.
Sunday breakfast? I tend not to eat breakfast – I like fasting. We’ll focus on Sunday lunch or supper. We’re big meat eaters.
Housework? I’m better at the cooking. It’s a cliché, but I’m rubbish at housework. If I’m going away for a few days as part of my job as an honorary colonel in the Marines, I need my uniform pressed, so I’ll get some Shara help with the creases.
Family activities? We always try to get cold at some point. We jump in the sea at any time of the year. I generally manage to persuade some of the family to join me.
Sundays growing up? Saturday was heaven, especially if I’d been away at boarding school – I was always homesick as a kid. On Sundays I started to feel sick again. I dreaded going back to school.
How do you prepare for Mondays? On Sunday nights l text Rupert, my best buddy who lives nearby, and say, ‘Let’s start the week strong. What about a workout in the morning and an ice bath?’ We have kettlebells and a big industrial freezer full of water on a circuit breaker, so it stays at one degree.
Sunday rituals? I’ve started wearing an old green, canvas kilt at home. I got it off eBay. I can get the wind around places where the wind doesn’t normally go, but the family gives me grief.
Last thing before you turn the lights off? Pray for my boys. I get the eldest to come and say goodnight and I put my hand on his head. He’ll say: ‘Come on Papa, get a bloody move on.’
