Hyrox is a running race.
Eight kilometres of it. Yet most athletes who enter Hyrox don't train like it is.
We've worked with a lot of Hyrox athletes over the past few years. They come in strong. Good gym base, solid conditioning.
They've put real time into the ski erg, the sled, the wall balls. The stations feel familiar. Comfortable, even. So that's where their training goes.
What they haven't trained is the running. And Hyrox has a lot of it. They'll do some cardio on the side, but it's usually unfocused and treated as an afterthought.
When we test these athletes in our lab, something comes up consistently. Strong bodies. Weak aerobic systems. Not weak as in unfit. Weak as in undertrained for what the race actually demands.
Race day makes it obvious.
The first couple of kilometres feel fine. The stations feel fine. Then somewhere around kilometre four or five, the wheels start coming off.
Not because they hit a hard station, but because the running has been accumulating, and their body isn't conditioned to handle that yet.
Here's the part I find genuinely interesting. When we improve someone's running, not only do they run faster, but their station performance often improves, too.
Not because they got stronger, but because they arrive at the stations less knackered. They can work at a higher percentage of what they're actually capable of when fresh, rather than scraping together whatever they have left.
That's the shift most Hyrox athletes need.
Not more time in the gym. More easy kilometres to build an aerobic base that lets all that strength actually show up on race day.
Strength gets you to the start line confident.
Running gets you to the finish line fast.
