I need to grow up and get better shoes. You can’t traipse around London for three days solid in worn-out Converse and not expect your feet to hate you by the end of it. Those soles are thin at their best, when they’re new, but when you’ve worn them the equivalent of ten times round the United Kingdom, you are definitely on course for some intense post-walk pangs de pied.

I spent a long weekend in London, two nights in a hotel were presented as a birthday gift by my boyfriend as a subtle hint to switch my brain off. It takes acts of bossy kindness like that from loving others for me to take the hint and accept I need downtime; enforced mini breaks, maternal rants, being strapped into a deckchair for a summer lobotomy. That kind of thing.

As part of the prescribed relaxation I decide to do away with the tube and walk everywhere. I wanted to see London. I didn’t want to zoom through underground tunnels and magically reach my destination without seeing anything; I wanted to join the dots overground. With my feet.

I wouldn’t ordinarily have the time to do it; trips into town are usually for one purpose and bookended by rushing. A rush to get there, a rush to get back. Occasionally I’ll manage to see friends when going in for a meeting or to do a show, but mostly I go there for the thing itself then dash away again. Time. It’s tricky to get it right, isn’t it?

But this weekend I walked. I strolled that bad boy London. I perambulated the nation’s capital like a boss. I mooched the living bejesus out of the big smoke.

And I remembered to look up. I was like a magpie for all the hidden bits; the old street signs, the plaques memorialising long-gone taverns, the chimneys and church steeples and turret rooms and broken windows and strange shops and old walls and hidden doorways and mysterious doorbells. Grandeur and hovels, side by side. Valiant preservation and cruel unthinking destruction. Things simply fading away under the weight of newness. Change. History. Time. My eyes were hungry for it all. I loved London that day in a way I had not allowed myself for a long time. Because I took the time to.

At one point, after picking up the pace again after a well-earned pint of lager and lime in Drury Lane, I wondered if my walking London might be a bit like where Forrest Gump starts running and keeps on going until he gets tired and just stops in the middle of a desert road, all beardy and pooped but with a yawn of strange clarity. I wondered if I might be silently protesting against something, hitting my feet against endless pavements driven by some inner voice until the voice just quietens and I would look down and realise I’d worn my legs down like pencil lead. Walking is meditative; it doesn’t just take your body to other places, it carries your mind away too. I think I needed it. Time and space and walking.

And then of course you get home after three days of being the Barbican’s answer to Bear Grylls and take your shoes off and wince and think maybe you should buy yourself some nice Scholls. “You’re 37 now, Hasler. It’s time. Those arches could drop at any minute.” You look at your feet – the same ones you’ve had all your life, the ones that have walked you everywhere – and you see your own history there, every room and street and moment you have ever walked through used those very feet – and you might even remember to thank them.
