“You're better than you think you are, and you can do more than you think you can,” Ken Chlouber, founder of the legendary Leadville Trail 100 ultra, tells runners at the start.

We've covered in detail how to prepare your body for an ultramarathon. But the truth is that after kilometer 50, 60, 70, it's no longer your legs running the race. It's your head. An ultramarathon is, first and foremost, a mental trial. Your body is capable of far more than you think. The trick is convincing your brain of it — because your brain will do everything it can to make you stop.

10.1. Your Inner “Compass”: Why Are You Here?

When it's 3 a.m., you're lost, you've run out of water and there are still 40 kilometers to the finish, your brain will ask you one simple question: “Why exactly are we doing all this?” And you must have a clear, cast-iron answer to it.

Find your “Why”: “I want to prove to myself that I can,” “I want to see the sunrise in the mountains,” “I want to be an example for my kids.” The answer can be anything, but it must be yours, sincere and very strong. Write it on a slip of paper and put it in your pack. In a hard moment it will become your most important “gel.”
Set three goals:
- The minimum goal (bronze): simply reach the finish. This is the main goal for your first ultra.
- The optimum goal (silver): finish within a certain time (say, 15 hours).
- The maximum goal (gold): make the top 50, or beat that guy from your running club. This system will protect you from disappointment if things don't go according to the “gold” plan.

10.2. Make Friends With Discomfort

An ultramarathon hurts. Period. You will chafe, ache and feel nauseous. Your task is not to avoid discomfort but to learn to accept it and work with it.

Turn the critic into an ally: there's an inner voice in your head that will whine: “We're tired, let's stop, why do we even need this?” Don't fight it. Negotiate. “Yes, I know we're tired. Let's run to that tree and eat a piece of candy. Then to that hill, and we'll listen to our favorite song.”
Eat the elephant one bite at a time: don't think about the 100 kilometers. It's demoralizing. Your distance is the next aid station. Made it? Great — the new goal is the next one. Small steps like that are how you eat the whole “elephant.”

10.3. The “Movie” in Your Head: Visualization

The best athletes “run” the race dozens of times in their heads before the start.

Play the film: close your eyes and picture the entire race. Here you are running the first kilometers with ease. Here you are confidently tackling a steep climb. Here you are at an aid station, quickly restocking.
Rehearse the crisis: what if it rains? What if your leg cramps? What if you get lost? Mentally run through these scenarios and your responses. When (and if) they happen for real, you'll already have a ready-made plan — and there will be no panic.

10.4. Zen on the Run: The Power of the Present Moment

An anxious brain constantly jumps between the past (“I should have started slower”) and the future (“oh god, I still have 50 km to run!”). Your task is to bring it back to the here and now.

“Ground yourself”: focus on what is happening right now. Listen to the crunch of gravel underfoot. Feel the rhythm of your breathing. Watch the play of light on the leaves. These are simple mindfulness techniques that restore your sense of control.

10.5. When It Hits: An Action Plan for the “Pit”

The “pit,” the “wall,” the “crisis” — it will happen, guaranteed. You'll feel total apathy, weakness and an urge to quit immediately. What do you do?

Systems check. Don't panic. Run a quick “check-up”:

Sugar? When did I last eat? Eat a gel. Right now.
Salt? When did I last take a salt tablet? Take one.
Water? Am I drinking enough?
Pace? Maybe I'm running too fast? Slow down or switch to hiking.

The 15-minute rule. Tell yourself: “I'll do all of this now and give myself 15 minutes. If I don't feel better in 15 minutes, I'll think about dropping out.” In 90% of cases, within 15 minutes the sugar and salt reach your blood, and life regains its colors.

📖 Case study: Dmitry, 42, first ultra, 80 km

Dmitry had prepared superbly: 5 months of systematic training, laboratory testing done, zones dialed in. The first 50 km of the race went like clockwork. Even heart rate, fueling on plan, feeling great.

At kilometer 55 a steep climb began. The sky clouded over and a cold rain started. The temperature dropped from +18 to +8. Dmitry was soaked to the skin. By kilometer 60 it hit him:

chills, trembling hands;
total apathy: “Why did I even come here?”;
thoughts like: “I have a wife and kids at home, and here I am suffering over nonsense”;
his pace dropped from 7:30/km to 10:00/km, and then he slowed to a walk entirely.

What Dmitry did (correctly):

Stopped for 30 seconds, took deep breaths: “Stop. Panic won't help me.”
Systems check:
- Sugar? The last gel was 40 minutes ago → ate two gels back to back.
- Salt? Had forgotten his salt capsules → took 2 tablets.
- Cold? Soaked through → pulled his spare windproof jacket out of his pack.
- Water? Had been drinking fine.
Remembered his “Why”: in his pocket he had a note: “I want to prove to myself that I can. I want my daughter to be proud of me.”
The 15-minute rule: “I'll keep going for 15 minutes. If it doesn't get better — I'll think about dropping.”
Broke up the distance: “I'm not thinking about the finish. I'm only thinking: reach the next aid station, 5 km away.”

What happened:

Within 10 minutes the glucose reached his brain. His legs started obeying again. He warmed up in the jacket. Within 20 minutes he was running an easy jog. An hour later he was at the aid station, drank hot tea, ate salted potatoes. Life had meaning again.

The finish: 11 hours 45 minutes. With a huge smile and a medal.

The lesson: the “pit” is almost always physiology (sugar, salt, cold, heat), not genuine weakness. Your brain is trying to trick you: “Drop out, you feel terrible.” Don't believe it. Run the systems check and give yourself 15–20 minutes. In 90% of cases the crisis passes, and you run on.

An ultramarathon is not about being the fastest. It's about being the most stubborn, the wisest, and the best at negotiating with yourself. It's a journey that begins long before the start line and doesn't end at the finish. And we hope this book becomes your reliable compass on this remarkable adventure. Good luck!
