Do you know how many kilometers per week champions run when preparing for marathon distance? From what I've heard and read, it is up to 200 kilometers per week. 200 kilometers per week is what athletes who are competing for breaking records do. I really like this fact because it speaks about volume. The volume is not only conditioning the body—it's mostly conditioning the mind. And that is what endurance at its core is about.

The Mental Threshold

If you are consistent and frequent in running 10 kilometers, your mind—of course your body as well, but your mind—knows that after 10 kilometers, you can relax. Your system has learned where the finish line is. This becomes your ceiling. This is the moment when, if you want to increase the volume of running, your mind is so strongly conditioned that after 10 kilometers you relax. The body prepares to stop. The mind signals completion.

Every time you want to push a little bit further, you're going to feel such intense emotional resistance. Not physical resistance—emotional resistance. Your mind has been trained to expect relief at 10 kilometers. When you try to go beyond that point, you're fighting against weeks, months, years of conditioning. That's why breaking through your current volume feels harder than it should. The body could continue. The mind refuses.

Condition for Double

So to me, I would like to condition my mind for double the amount that I want to be competitive in. If I want to be competitive in 10 kilometers, I would like to condition my mind for 20. Not because I'll race 20 kilometers. But because when I race 10, my mind knows there's more capacity. The finish line comes early. There's reserve left. The mental threshold has been pushed far beyond what's required.

Speed is a completely different topic. But let's take this principle to other areas of our lives. Volume matters because volume is more data. Volume is basically failing more. Volume is bigger capacity. You can always do less when you have bigger capacity, but doing more with limited capacity feels extremely exhausting. When your ceiling is exactly where you need to perform, every performance becomes maximum effort. When your ceiling is double, performance becomes sustainable.

Volume Equals Data

More volume means more repetitions. More repetitions mean more failures. More failures mean more adjustments. More adjustments mean more refinement. This is the data. Not information from a book or a screen. Data from your body. Data from your mind under stress. Data from the moments when you wanted to stop but continued. Data from the moments when you did stop. Data from comparing those two experiences.

When you increase volume, you're not just getting stronger. You're collecting evidence. Evidence of what works. Evidence of what breaks you. Evidence of where your mind deceives you about your capacity. Evidence of where your body actually needs rest versus where your mind wants comfort. This evidence becomes your foundation. Your confidence. Your ability to predict and navigate difficulty.

The Blessing of Knowing

When it comes to endurance, the biggest and most amazing gain—emotionally and mentally—is being able to know that I can trust my body for 40 kilometers, because I've done it. Not once. Not in perfect conditions. I've done it tired. I've done it unprepared. I've done it when I didn't want to. I can predict with very good accuracy at what point my mind is going to start breaking because of the pain in the body. And it's not a surprise.

When it's not a surprise, the friction is much less emotionally and mentally. Then I actually make a very conscious choice. Should I give into the pain and slow down? Or—knowing that the pain is coming, knowing that it's going to get exhausting for my mind—can I consciously choose to slow the pace but keep moving? This is the difference between reacting and choosing. Reacting happens when you're surprised. Choosing happens when you know.

The Experience You Cannot Skip

That knowledge is the blessing of the experience. And you cannot skip the experience. You cannot read about it. You cannot watch someone else do it. You have to accumulate the volume yourself. If you have done 80 kilometers, you just know. You know you can push through—even slower, even in an imperfect way—but you can finish it. That knowledge doesn't come from one perfect run. It comes from volume. From the accumulated experience of showing up when it's hard.

That's the blessing of the volume. Your mind is stronger. Your character is stronger. You know how to persevere. Not because you're motivated. Not because you had a good day. But because you've done it enough times that perseverance has become your default response. That's what 200 kilometers per week builds. Not just a faster marathon time. A mind that doesn't quit.

Volume matters.
