The mountain dwarfs Catania, a city of a million. Snow-capped and pyramidal, Etna looms moodily, shifting endlessly from shrouded and mysterious to clear and triumphant. We’re winding our way to it.

On the Uber ride up from our apartment, the driver, Mr Orazio, turns up Spotify. His car is a suitably Sicilian shade of black. He loves Queen, Pet Shop Boys, and Sowing the Seeds of Love by Tears for Fears — a glorious 1980s song I’d forgotten, all late-Beatles melody and borrowing the trumpet line from Penny Lane.

Decanted near a forest by Mr Orazio, we’re rescued by a pair of parkrun locals.

The pre-run briefing is punctuated by one-liners from local senior men. A dog is introduced and becomes comic material too. Most laugh. I do, too, although the jokes are in rousing, excitable Italian which is beyond me. I suspect this is true for many as we’re from Dublin, Poland, and Lincolnshire. Oh, and Austria — Australia.

The ceremony concludes with the Run Director holding up his phone and pushing play on a robotic but impeccably Oxford English translation: ‘You are warned to take care. The path can be dangerous.’ With ample reason, as we were about to discover.

Four laps on Mount Etna, Europe’s largest active volcano. The course twists through pine forest over black volcanic soil and scattered lava rocks, with tree roots and rough terrain. Camp firepits dot the forest floor. Broken glass prickles around these. Watch out!

The Ionian Sea, cobalt and shimmering, lies quiet and to the east. Below, Catania is still awakening on its smoggy coastal plain. It’s too early, I imagine, for our neighbourhood cats to have begun meowing to each other in their feline chorus.

Nearby, roaring engines from the Italian South Mountain Speed Championship provide an appropriately seismic soundtrack. Whilst the throaty crackle of automotive speed surrounds us, nobody here seems overly concerned with swiftness.

Claire decides to walk a lap. Generously, she takes photos and videos. We intersect twice and each time she chirps marital encouragement through the trees like, ‘Ole, ole!’ and ‘Go, you!’

There is welcome shade although this provides me with limited athletic assistance. I stumble my way along the forest trail, twisting and climbing before descending into a grassy field. The motorsport enthusiasts have helpfully backed their trailers onto our already narrow path. Meanwhile, Fiat fug smothers the course.

Crossing the finish line for the fourth and final time, volunteers wave and applaud with affectionate energy. I stagger to my water bottle. I’m cooked. At least, Etna hasn’t erupted, hurling lava onto my now simmering head. One of the English runners has taken a tumble and her knee and palm are reddened.

Afterwards, cake and biscuits are shared, and stories are traded beneath the pines. We record our names in an exercise book — relevantly enough — and leave comments in another notebook like we’ve been to a holiday house and had a grand weekend of laughter and communal meals and carafes of wine. In a way, it is. Scribbling a few kind words, I feel appreciative.

I finally meet core volunteer Mimmo with whom I’ve exchanged messages. He hugs me warmly. Twice.

Claire and I stroll down the mountain to the unclouded village of Nicolosi for coffee and pistachio cannoli.
