The Mental Side of Ultra Endurance: How to Keep Going When Your Body Wants to Stop

From the outside, ultra endurance looks like pure suffering. From the inside, according to the athletes who actually do it, it's mostly about structure — pacing, energy management, and what you tell yourself in the moment your mind says "that's enough."

You don't win an ultra in the first hour

Both Bart Maljaars and Tristan Olij point to the same early mistake in their interviews: starting too fast. Ego at the start line, logic switched off. You can only lose an ultra in the first hour — you can't win it there.

The fix is deliberately controlled pacing, sometimes even uncomfortably slow, at an effort you can sustain for hours while still eating, drinking, and thinking clearly.

Make the race small

Bart's approach when his body feels empty but the race isn't over: stop thinking about the total distance or time. Focus only on the next point — the next kilometer, the next few minutes. That's what keeps a runner in control when the full scale of what's left would otherwise be overwhelming.

Structure beats motivation

Tristan Olij, training 25–33 hours a week toward the Ironman World Championship, doesn't rely on motivation to show up. He rarely struggles with a lack of it — because the structure of his week removes the need to decide every day whether he feels like training. Every session has a specific purpose, which is what lets him handle high volume without overloading.

That's a pattern worth taking from elite endurance athletes generally: motivation is unreliable. Structure isn't.

Accept that it hurts

Both athletes are direct about this: pain is part of ultra, not a sign that something has gone wrong. Fighting it makes it worse. The alternative — accepting it as the moment you trained for — is what lets the pace hold instead of collapsing.
