WHY I SWITCHED TO CROSSFIT AND HYROX AFTER TWO DECADES OF ENDURANCE RACING

Somewhere around the fourth Ironman, I stopped being a man who did triathlons and became a man who was one. Nobody announced the change. It happened the way most identity shifts happen — quietly, one race cycle at a time — until the thing you do is the thing you are, and you can't quite remember the version of yourself that existed before the training log did.

I've been racing since 1987. Triathlon specifically since 2007 — nineteen years, at a pace of two to three big races most years. More than 300 finish lines across triathlon, Hyrox, Spartan, Tough Mudder, and CrossFit competition. I built an identity on purpose, and it held me together through years when a lot of other things weren't holding. A finish line is an honest thing. It doesn't care about your excuses, and it doesn't lie to you about whether you showed up.

But an identity built entirely on finish lines has a problem nobody warns you about at mile one of your first race: it doesn't know how to end. It only knows how to sign up for the next one.

The Question Nobody Asks at the Start Line

Every endurance athlete gets asked why. Why the early mornings, why the entry fees, why the vacation days spent standing in a wetsuit at 5 a.m. in a parking lot instead of on a beach. Most of us have an answer ready — discipline, community, the challenge, proving something to yourself — and the answers are true as far as they go.

What almost nobody asks is the harder question: if the races stopped tomorrow, is there still a person standing there, or was the person mostly built out of the races? I didn't have a good answer to that for a long time. Somewhere around year eight or nine, the sport stops adding to the identity and starts being the identity, full stop — and that's a different, more fragile thing.

The high is real. Crossing a finish line after seventeen hours of moving is one of the cleanest, most honest feelings available to a human being. But the low three weeks later — when the next training block hasn't started and the last one is over — gets talked about a lot less. Race organizers build entire marketing campaigns around the high. Nobody builds anything around the gap.

I Finally Added Up the Actual Numbers

This isn't a confession. Three hundred finish lines is a resume, not a regret. But a resume has numbers on it, and I'd never actually sat down and added mine up until I started digging into what nineteen years of triathlon specifically had cost — not vaguely, but honestly.

A single Ironman-distance race doesn't cost you the day you race it. It costs you the training block that made the race survivable — sixteen to twenty-four weeks, ten to twenty hours a week. Run that across nineteen years of consistent racing and the honest total lands somewhere in the range of 7,000 to 11,000 training hours — not counting travel, race-day hours, or recovery weeks that still involved structured movement. That's close to the time investment of a second full-time job, run in parallel with the first one, for the better part of two decades.

The dollar number is just as real. Entry fees, coaching, gear, travel, physical therapy for the inevitable overuse issues — run across nineteen years, the honest total sits somewhere between $55,000 and over $100,000. Nobody frames a first half-Ironman sign-up that way. By year nineteen, calling it a hobby is a category error.

The Column That Actually Made Me Look Twice

Time and money are recoverable. A man who's spent too much of either can, in theory, simply stop spending it. Cumulative joint and connective tissue wear doesn't work that way. Cartilage doesn't regenerate the way a bank account refills.

What moved me from "interesting research" to "I need to actually do something about this" was the cardiology literature specifically. There's a real, peer-reviewed body of research — published in mainstream cardiology journals, not a fringe theory — documenting structural changes to the heart and large arteries in athletes who chronically train for and compete in extreme endurance events. A large, long-running Copenhagen population study found the relationship between exercise duration and mortality isn't a straight line that keeps improving the more you do — it's U-shaped. Moderate volumes of vigorous activity associate with the strongest mortality benefit; volumes well beyond that don't keep buying more benefit, and past a certain point the curve bends back.

Two findings inside that research landed hardest. First, lifetime vigorous endurance training has been identified as an independent risk factor for atrial fibrillation, separate from the usual suspects like hypertension or obesity. Second, imaging studies comparing veteran marathon runners against age-matched, less active controls have found no protective effect on coronary artery calcification — in some comparisons, calcified plaque volume runs equal to or higher in the highly trained group. A man judging his cardiovascular risk purely by his training volume, rather than by an actual scan, is judging it by the wrong instrument.

None of that is a reason to panic, and none of it means my nineteen years were a mistake. It's a reason to get an actual cardiology workup instead of assuming decades of racing already answered the question — and it's the specific piece of research that made me start asking what I should be training instead of just how much.

Why Hyrox and CrossFit, Specifically

What I found on the other side of that question wasn't a reason to quit. It was a redirect: grip strength, power output, mobility — the things nineteen years of aerobic volume never trained — delivered in a fraction of the weekly hours racing demanded. Not instead of the athlete I've been. Alongside him, finally measuring the things that actually predict the next twenty years.

You'd also not be doing something strange by making this switch — you'd be stepping into something that's already scaled. Hyrox started as a small event in Hamburg in 2017 and has grown into a large international race series with a participant base too big to dismiss as a fitness fad; many entrants are first-timers, and the field isn't limited to young specialists. CrossFit's competitive numbers have moved up and down rather than climbing in a straight line — worth saying plainly rather than pretending otherwise — but the underlying training methodology, and the research base building around it for older adults specifically, hasn't declined at all.

There's a structural reason both formats retain people at rates that would make most endurance race organizers jealous. Triathlon, for almost everyone not racing professionally, is a fundamentally solitary sport wearing a community costume — you train alone most mornings, and the community exists at the race expo and the post-race beer tent, bookending months of solitary miles rather than living inside them. Hyrox's doubles and relay divisions, and CrossFit's fixed 6 a.m. class with the same six or eight people three or four mornings a week, invert that structure entirely. You don't need to like the people in your class. You need them to notice if you don't show up — and that alone changes the calculus on the mornings when nothing else would have gotten you out of bed.

What This Isn't

This isn't the anti-triathlon take. I've crossed more than 300 finish lines and I'm not disowning a single one of them. If nineteen years of racing is still what lights you up, nothing here argues against continuing it. What actually changed is narrower than a verdict: a body past fifty benefits from training the things endurance volume alone doesn't train — grip strength, power output, mobility — regardless of whether endurance racing stays part of the picture or gets redirected entirely.

The identity doesn't have to end. It has to get more accurate about what it's actually measuring. For nineteen years, the measurement was distance and duration — how far, how long, how much sustained output a body could produce. That measurement was never wrong. It just stopped being the only one that mattered.

For educational purposes only. Not medical advice. Consult your physician before making changes to your training, especially if you have a long endurance-training history and haven't had a recent cardiology workup.
