The idea for WattsWrong basically started the day, now a long time ago already, when I put my name down for the Belgian Dodentocht aka the “March of the Dead.” It’s a 100 km sufferfest that’s technically a walk, but somewhere along the way people decided it’s fun to run, too. I did it. It went… badly. I finished (thank you), but the debrief from friends and family was unanimous: What’s wrong with you? Midlife crisis? I like to think I’m a tad young for that. Or not. Who knows.

Naturally, I followed that up by stacking a few marathons in a row, purely as an experiment to see what my body would do. Same question: What’s wrong with you? This time from my dear wife as well, which, honestly, is fair.

Then I signed up for a full Ironman, the kind that takes 10 hours or more. And, predictably: What’s wrong with you?

Along the way, I had my own questions. About training. About fueling. About pacing. About shoes, bikes, wetsuits, watches, and which tiny piece of carbon or rubber might actually make a difference when your legs are threatening a mutiny. Some answers I found the hard way. Some I’m still figuring out.

That’s what this site is about: finding watts, and, more specifically, finding what’s wrong. I’ll share the mistakes, the good moments, the sessions that were a waste of time, and the ones that somehow worked. You’ll get honest, enthusiast-driven notes from the field: endurance, running, triathlon, ultras, the occasional bad idea, and everything in between.

There will also be gear talk. Because this hobby gets expensive fast, and it helps to know where your money is best spent.

If you’re into endurance sports, triathlon, Ironman, or the fine art of seeing how far stubbornness can take you, pull up a chair. Let’s figure out the right watts, and all the watts wrong, together.

Onwards.
