I hike across Manhattan this morning to pick up my runner’s bib and electronic chip for the New York City Marathon. I’ve run this event four times before; somehow the Kenyans always beat me. On the last occasion I placed 6000th of 36,000 runners and felt pretty pleased with myself. That was about 1998. That was twenty years ago, in the lives of humans, a full generation. A generation on, my body tells the story of my degeneration.

The sun shines, the autumn leaves glow gold and blush red. The thronging streets empty into the Jacob Javitz Convention Centre. THe human tide washes me before it and sets me down gently before overhead signs that read: BIB NUMBERS 1-100; NUMBERS 100-1000 and so on, all the way to Numbers 70,000-80,000. My number is 57,072. The bib persons shine their smiles of American teeth at me. They welcome me. From Australia? Wow! How old are you? Wow!

I approach the line where you try on the official souvenir shirts for size. In America the seats in airport lounges are very wide. In this country I think I’ll be a SMALL. The SMALL t-shirt is tight and smells richly of the hundreds who’ve sweated within it before me. I need MEDIUM. To my left a dozen or two women of all shapes and ages tear off their shirts and expose their underwear. An unexpected display. They do this to try on the souvenir shirts for size.

I wander aimlessly around the vast hall in a beatific state. Accents of all nations, shirts of all nations, languages enough for Babel, smiles, smiles on all sides. What – as the poet asked – is all this juice and all this joy? Unbidden, unchanging, my own teeth have organised themselves into a crooked grin. This huge assemblage, all for the simple task of bib-getting and shirt-receiving; these mere thousands here of the many tens of thousands who’ll run with me on Sunday all look idiotically happy.

Why? For what? Eighty thousand adults all gathering for play. Eighty thousand innocents.

As I leave the happy concourse and thread my way through the incoming thousands I pass two police officers. They wear bullet-proof vests and helmets. They grip in their arms their weighty submachine guns. Fifty-one marathons down and I’ve never seen this before. But something broke last Shabbat in Squirrell Hill. A fabric was torn in Boston in 2013. When they told me then the race was called off because bombs had gone off I kept running. I would not believe it. This, this glorious foolishness was the marathon, this the ceremony of innocence.

Feeling mounts within me. The physiology of imminent weeping signals intensity. It comes to me that this might be my last one. And if it be the last, ‘What larks, Pip old chap! What larks!’
