My first marathon at 42.

Notes on training, taper, and the very specific calm that arrives at kilometre thirty — and what every kilometre of it taught me about running a company.

Plate I · Frankton trail, 32 km · early autumn

Two weeks out from my first marathon I noticed something I should have noticed in the boardroom a decade ago. It was a small thing — a thought that came mid-run, somewhere on the Frankton trail with the lake going silver to my left — and it has been quietly rearranging how I think about leading a team ever since.

The thought was this: pace beats heroics. Always. The longer the distance, the more obvious it gets. And almost everything I do at work is a distance event.

What pace really means

For most of my twenties I confused pace with effort. I thought a "good week" at the company was the one where I'd been the most exhausted by Friday. I thought the engineers I admired most were the ones who had stayed up the latest. None of that was true; I just hadn't done the long runs yet.

"Pace is a kind of honesty about what you can do tomorrow, the day after, and in week eleven of the training block."

A marathon training plan does not care how heroic week three feels. It cares whether you can still run when you reach week eleven. Twelve. Sixteen. You either pace, or you don't finish. There's no other option, and the discipline of accepting that — out loud, in your training log — is the part that transfers.

The taper, applied

The taper is the part nobody warns you about. You spend twelve weeks teaching your body that more is better, and then in the last fortnight you have to teach it the opposite: less, slower, easier. Most runners hate the taper. I had to learn to like it, and the way I learned was at work.

Every product cycle has a taper. The week before launch is not the week to add a feature; it's the week to write the runbook, sleep, and trust the work you've already done. We've gotten this wrong at Scannable plenty of times. We've also gotten it right, and the difference shows up months later in retention curves we didn't know we were affecting.

Kilometre thirty

Everyone told me about kilometre thirty. Nobody quite captured it. There's a calm that arrives — not exhaustion, not euphoria, something quieter. The chatter falls away. You stop checking your watch. You're just running, and you've been running for a while, and you'll be running for a while longer, and the only thing left is to keep doing it well.

Notes for the team

I've started talking about pace in sprint retros. Not as a metaphor — as a real question: are we running at a speed we can maintain through week eleven of this cycle? The answers have been surprisingly honest, and the decisions that followed have been better for it.

The marathon is in nine days. I don't know what time I'll finish. I know I'll finish, because I paced, and because I trusted the taper, and because I've been doing the long runs since January. That's the whole lesson, really. There isn't a shortcut. There's just the work, done consistently, at a speed you can maintain.
