Why completing an Ironman at 40 was the most important business lesson I ever learned.
I want to tell you about the moment somewhere around kilometre 34 of the marathon — the last leg of an Ironman triathlon — when my legs had stopped working in any conventional sense, my vision had narrowed to the strip of tarmac directly in front of me, and every rational part of my brain was composing a perfectly reasonable argument for stopping.
I didn't stop. Not because I'm some elite athlete. Not because I had superior training or genetics or mental fortitude. I kept moving because I had made a decision 14 months earlier that I was going to finish this thing — and in that moment, the decision was the only thing left.
That's the lesson. The decision precedes the capability. And it applies to every company I've ever built.
People asked me why I chose to do an Ironman specifically at 40. The honest answer is that 40 felt like a meaningful deadline. Not because I was afraid of what came after — I wasn't — but because I wanted to prove something to myself at exactly that moment. That the body I'd been somewhat neglecting in my 30s while building companies was still capable of something extraordinary. That the discipline I applied to business could transfer to physical endurance. That I wasn't finished becoming.
The training took 14 months. Early mornings on a bike before the city woke up. Long swims that felt endless. Runs where I calculated and recalculated whether the pace was sustainable. And somewhere in those 14 months, something shifted. The training stopped being something I was doing and became something I was.
"The training stopped being something I was doing and became something I was. That shift — from external commitment to internal identity — is the same shift that separates founders who make it from those who don't."
I've built four companies over 25 years. I've experienced acquisition, failure, and the $300M exit. I've hired and fired, pivoted and persisted, celebrated and grieved. And the framework that best explains the difference between success and failure in all of it is the same framework that gets you across an Ironman finish line.
I crossed the finish line at Ironman Austria as the sun was setting. My legs had nothing left. My family was waiting. The announcer said my name — as they do for every finisher, professional or not — and something that I can only describe as a complete circuit closed somewhere inside me.
Not because I had done something special. Because I had done something I said I would do. Over 14 months, through early mornings and setbacks and moments where stopping seemed completely reasonable, I had kept going. And now it was done.
I've had company exits worth more money. I've had product launches that received more press. I've had professional moments that carry more conventional prestige. None of them felt like that finish line felt.
Because none of them required that particular quality — the one I now believe is the most important quality in both sport and business: the willingness to keep moving when everything reasonable says to stop.
Persistence isn't glamorous. It doesn't make for great highlight reels. But it's the thing. In endurance sport, in entrepreneurship, in most things worth doing. It's the thing.
