There's a Japanese word, Misogi, that originally meant a purification ritual. You washed under a waterfall to start clean.

Jesse Itzler ported the idea into the performance world. The modern version: once a year, do one thing so hard that you've got roughly a 50% shot of failing it.

It's a single annual challenge. Big enough to mark the year. Uncertain enough that you don't know if you'll come out the other side.

I picked up the practice 3 years ago. My version lives inside obstacle course racing. I race Spartan For me, my goal is to complete an obstacle course race every quarter. One of those races each year is the Misogi.

The rule, in one sentence: pick one thing a year, with a 50/50 chance of failure, that won't kill you.

Two parts matter.

It has to be uncertain. If you know you can do it, it isn't a Misogi. The whole point is the gap between who you are now and who you'd have to become to finish.

It has to live on the calendar. A date on the schedule that the rest of the year orients around. Without the date, it stays a daydream.

It rewires your identity. When you attempt something way outside your comfort zone, you break the ceiling on what you thought you were capable of.

It marks the year. Comfortable years run together in memory. Years with a Misogi inside them stand on their own. Three years from now you won't remember March, but you'll remember the day you signed up for something terrifying and finished it.

It compounds across a decade. Whether you win the Misogi or fail it, you walk out with a different sense of what you can survive. Stack 10 of those and you've built a different person.

If you know with certainty you can do it, it’s not a Misogi.

Here’s how to set yours:

Step 1. Make it absurd for where you are right now. Absurd is relative. If you've been sedentary for a decade, a 5K is absurd. If you've been training for years, the absurd version is a 50-miler or a multi-day event. Calibrate to your real starting point, not someone else's highlight reel.

A few examples across the difficulty spectrum:

Step 2. Set the difficulty at genuine uncertainty. Aim for the edge of believable. Far enough out that you might fail, close enough in that you might not.

Step 3. Commit on the calendar. Sign up, pay the entry fee, and tell at least three people who'll keep asking you about it. This is what locks the practice in.

Step 4. Train the gap. Ideally a Misogi runs for anywhere from 3 to 12 months of preparation. Those months are where most of the growth actually happens. The event is the receipt at the end.

Not every Misogi has to involve a finish line.. For some, it might look like:

If there’s a voice inside saying “I could never do that”, that’s where you need to go.

If you stay in the game for 30 more years, that's 30 Misogis.

Thirty moments where you pushed yourself past your limits. Thirty identity shifts. Thirty unforgettable years.

You won’t remember every Tuesday at the office. But you will remember the year you ran an ultra, the year you hiked that mountain, or the year you committed to 365 straight days of meditation.

This is how you build a life story worth telling.

👉 Pick one thing a year with a 50/50 shot at failure. That's the Misogi.

👉 Calibrate to where you actually are.

👉 Put it on the calendar. Sign up, pay the entry fee, tell people who'll hold you to it.

👉 Spend 3 to 12 months becoming someone who can meet it. The training is the growth.

👉 Stack a decade of these and your sense of what's possible has been rebuilt from the inside.

What would make this year unforgettable? Name it before the end of the week. The first move is the commitment.

Plan it. Commit to it. Attempt it.

Your future self will thank you.

Stay well,
