One brutal thing a year, done in the wrong order

Once a year I do one thing that might not work.

The current version: an ultra Ironman, raced in reverse. Marathon first. Then the bike. Then the swim.

People assume the reversal is for the aesthetics of it — that doing a familiar thing backwards is the sort of gesture that photographs well. It is not. The order is the whole point, and it took me a while to be able to explain why.

#What a Misogi is supposed to do

The word comes from a Japanese purification rite; the modern usage I took it from is simpler. One event a year, hard enough that the outcome is genuinely uncertain. Not a challenge you will complete if you train properly — one where you might not.

The uncertainty is load-bearing. A hard thing you are confident about is a workout. It builds fitness and it builds nothing else. A thing you might fail restructures how you relate to difficulty for months afterwards, and it does that specifically because at some point during it you have to decide, with no audience and no benefit, to keep going.

The failure has to be real or the mechanism does not fire.

#Why the order is reversed

A standard Ironman is swim, bike, run. That order is deliberate and humane: the swim is the most dangerous and comes when you are fresh, and the run is the one you can survive on will alone.

Reversing it removes the humane part.

The marathon first means you enter the bike leg on legs that are already finished — not tired, finished, the specific hollow that only shows up somewhere after thirty kilometres. Everything after that is done from a starting position of depletion rather than working towards one.

And then the swim is last. That is the sharp end. Swimming is the discipline where fatigue is most dangerous and where technique degrades fastest, and I arrive at it with nothing left. There is no coasting in water. You cannot freewheel a swim.

So the reversal takes an event that is designed to end at your limit and rebuilds it to begin near your limit and then keep asking. That is a different experiment.

#What it is actually training

Not endurance. My endurance improves far more from ordinary conditioning work done consistently across a year than from one day of this.

It is training the thing that happens at hour six when the reasonable decision is available.

Every hard endeavour has a moment where stopping is defensible. Not shameful — defensible. You could stop, you would have a real reason, nobody would think less of you, and you would be warm and dry in twenty minutes. In a business that moment arrives when a launch has flopped and pivoting looks prudent. In a company it arrives when a founder says the market is not there. Sometimes stopping is correct.

The problem is that at that moment you cannot tell whether stopping is correct or whether you just want to stop, because both feel identical from the inside. They present with the same reasoning, the same tone, the same air of maturity.

The Misogi is the only setting I have found where I can practise being in that moment with the answer already known. I know I should not stop, because the whole design of the day is that finishing is the objective. So the internal voice producing extremely reasonable arguments for stopping is, definitionally, wrong. And I get to sit with it, for hours, knowing it is wrong, and go anyway.

You cannot get that from a workout you will obviously complete.

#What it is not

It is not a metaphor for business, and I would rather not pretend it is. Building a company does not require this. Most of the best operators I know do nothing like it.

It is also not proof of anything. Nobody should be impressed by an amateur doing a triathlon in an unusual sequence; there are people who do far harder things routinely and do not write about them.

And it is not sustainable as a lifestyle. Once a year, specifically. The whole value comes from its rarity — the annual cadence is what keeps it a real event rather than a training block, and something with a genuine chance of failure is not something to hold in your body more than once every twelve months.

#The part that surprised me

The benefit does not arrive on the day. On the day I am mostly just cold and in pain and thinking about very small things — the next kilometre, the next hundred metres of water.

It arrives about three weeks later, in something completely unrelated. A call I have been avoiding. A piece of work that has gone badly and needs to be redone from scratch rather than patched. The thing I notice is not courage exactly. It is that the internal argument for avoiding it sounds familiar — it has the same texture as the one at hour six — and recognising the texture is enough to discount it.

That is the whole return. One day a year buys a slightly better ear for my own excuses.

It is worth it.
