I’m jogging west along Adelaide’s most distinguished boulevard on this dazzling Sunday morning. Much of this street I’ve never explored.

The footpath is wide and tree-lined, and the streets are hushed, empty. The warm weather’s more akin to October and not late May so I flip between viewing this as serene and approaching apocalypse. Claire had an Auslan interpreting job at the Lion Arts Factory — a burlesque dance competition — so we decamped to the Intercontinental (Hotel not a nuclear-armed ballistic missile).

Next door, the Adelaide Convention Centre sprawls— so vast, Boeing could assemble planes in it. I enjoy it best at big events like the Cellar Door Festival when over splashes of red wine and among the Merlot-ed masses, Claire and I whisper in snug, secretive ways.

I pass the medical precinct ­— towering, assured, glittering — on which I’ve never set foot. Formerly overlooking the railyards, it was the road to nowhere. Like much of our privileged world, its function has transitioned from industrial to knowledge, a Victorian badlands to a district of profound applied intellect.

A duo of male joggers materialises. Relaxed with each other, they’re chatting comfortably. We exchange a chirpy round of, ‘Morning.’

I cross the terrace at the Royal Adelaide Hospital. It’s among the most expensive buildings on the planet. With relief rather than pride, I nod at this thought. Nuclear plants, much of Singapore, and those futuristic Gulf state mirages, all sit higher up the list. Even the American football stadium at Inglewood, in LA, cost more (five billion) and yet much of it is (fake) grass. How could this be?

The Newmarket Hotel stands silent, a ghost ship. Its legacy is to the nomenclature of glassware with the butcher, named for the small beer preferred by abattoir workers at lunchtimes. Where can we now find these 200ml tumblers? Maybe in lonely country pubs. Are these victims of the American (read: global) trend for upsizing?

Peering in at a cluster of UniSA buildings, it’s another mysterious pocket of North Terrace, an architectural Siberia. The intriguingly named Elton Mayo building (a pianist and salad dressing hybrid) has an almost mocking confidence. One day, I should stroll in. He was a celebrated psychologist.

Striding along now. The Oaks Horizon. We had a couple of stays there with my boys to explore the city. I wanted them to experience Adelaide’s cultural riches and investigated the Botanic Gardens, Museum, and Art Gallery. We also played mini-golf at Holey Moley near Hindmarsh Square. Education complete at the Pancake Kitchen.

Red and blue flashing lights and my heart quickens. What? Why? A paused police car menaces a white SUV just by the Stamford Plaza. I amble through during that tense interlude when the car-of-interest stops and the pair of police alight — adjusting their belts, straightening their navy caps — and I imagine the driver’s halting, ‘Morning, Officer. Is there a problem?’ What has gone badly at breakfast on this Sunday?

A convenience store window offers a super deal: two unlikely allies finally together — Farmers Union Iced Coffee and a ham and cheese croissant. I’m proud that South Australia is one place where Coke is outsold — Glasgow and its carbonated Irn-Bru being another. Bravo, iced coffee! Take that Paris! Take that Rue du Faubourg Saint-Honoré! Take that Atlanta!

No traffic. Flouting the crossing light’s red man, I scurry over King William Road. I see solitary pedestrians, the homeless interrupted by dawn into forlorn, shuffling movement and I’m grateful for my fortune. Turning around at the former Botanic Hotel, there’s evocations of my untroubled university life. The building’s majestic, its raucousness now becalmed.

With the sun on my face, the future technopolis of Lot 14 swims into view. It’s only hoardings and a barren block but could erupt suddenly, all dazzling glass and steel. Taking in the University of Adelaide and Bonython Hall’s honeyed façade, I’m reminded, not unjustly, of Bath and Oxford.

This is a handsome boulevard.

Kintore Avenue dips down to the River Torrens and hosts the State Library. I spent hours there at uni — the reading room’s newspapers (Ooh, there’s the Wagga News) and borrowing Steely Dan cassettes to play in my HQ Holden. The ease of shaping my days with leisure and study.

Adelaide remains tranquil and I again spy the pair of male joggers. They’re still nattering and unbothered by exertion. It could be a pre-coffee pretense.

The casino emerges. Australian cities have increasingly thorny relationships with these, and glamour has largely given way to wretchedness. Seeking dinner last night, Claire and I foolishly walked through one of its eateries. Glaring lights. Cafeteria tables. All the allure of a Soviet hospital. We declined.

Adelaide Casino’s a boorish, puffed-up pokies barn. You could get in wearing double-plugger thongs. Nearly. It annexed the splendid Railway Station. But I remember being disgorged from the Gawler train in the 1980’s, heading to the one-day cricket and this rushes back to me, riotously. Eskies, flags, Adidas Romes. AB, whistling kegs, zinc.

I jog on, buoyant, smiling at my younger self and his friends.

Outside the Intercontinental’s an idling fire truck with Technical Rescue emblazoned on its side. Ignoring these blue and red lights, the hotel elevator then ejects me on the seventeenth floor.
