Positive Self-Talk in Racing: Phrases to Replace "I Can't Go On"

Introduction

“I’m dying.” “I’ll never make it to the finish line.” “I shouldn’t have come.”

These words are silently repeated by countless runners every year on Ren’ai Road at the 32-kilometer mark of the Taipei Marathon. Self-talk is the ongoing internal communication we have with ourselves, and research shows it has a significant impact on athletic performance—positive self-talk can delay the perception of fatigue and maintain steady pacing; negative self-talk accelerates the urge to quit and can even trigger actual physiological breakdown.

The problem is that at the toughest moments of a race, “thinking positive” is easier said than done. This article isn’t about pretending you’re not tired; it’s about providing a scientifically grounded system for replacing your words.

The Science Behind Self-Talk

Sports psychologist Antonis Hatzigeorgiadis’s research categorizes self-talk into two main types:

In long-distance running, the most common failure comes from a breakdown of motivational self-talk: when the body’s fatigue signals are interpreted as “I’m dying” rather than “I’m adapting to the challenge,” the central nervous system prematurely activates a protective fatigue mechanism, forcing you to slow down.

The Most Common Negative Phrases and Replacement Scripts

“I can’t go on”

The problem with this phrase is that it presupposes an “end”—you’re about to collapse. The replacement strategy is to chunk your time frame:

❌ “I can’t go on.”
✅ “I just need to make it to the next water station. I’ll worry about the next segment when I get there.”

This strategy is called “chunking”—breaking an impossible whole into a series of manageable small segments. Taiwan’s major marathons have aid stations every 2.5 kilometers, providing natural psychological break points.

“I’m too slow, everyone is passing me”

This is the social comparison trap. The replacement strategy is to return to your own reference point:

❌ “That woman just passed me. I’m really too weak.”
✅ “I’m running my own race. Where my body is right now is the best I can do today.”

The essence of a marathon is a dialogue between a person and the distance, not a competition between people (unless you’re in the elite group). Many runners who pass you at kilometer 30 may hit the wall and collapse by kilometer 38.

“My legs are completely out of strength”

This is a classic case of amplified physiological signals. The replacement strategy is signal reinterpretation:

❌ “My legs are out of strength. I’m done for.”
✅ “My legs are working hard, and this is a normal fatigue response. My heart and lungs are still fine. Keep moving.”

Research shows that a large portion of the “muscle weakness” felt in the latter half of a long-distance race is protective inhibition from the central nervous system, not actual muscle depletion. As long as you keep moving, the feeling often subsides within a few minutes.

“I’m not in good form today. Forget it.”

This phrase is the most dangerous because it gives quitting a “rational” excuse. The replacement strategy is to redefine success:

❌ “I’m not in good form today. Slowing down by an hour makes it pointless.”
✅ “Today is harder than expected, but finishing is today’s goal. Every step counts as training.”

How to Build a Personalized Self-Talk Script

Effective self-talk must be personalized and practiced in advance. Here are the steps to build your script:

1. Recall your breaking points: Think about which kilometer mark you’re most likely to give up at, and what words go through your mind at that moment
2. Write down replacement phrases: Design 2–3 personalized replacement phrases for those negative statements
3. Test them in training: During the final 20% fatigue phase of your long runs, deliberately use the replacement phrases and observe the effect
4. Keep it short: Your brain doesn’t have the capacity to process complex sentences during a race—trim your replacement phrases down to 3–5 words
5. Design a trigger word: Choose a “reset word” (such as “start over,” “rhythm,” “keep going”) and trigger it the moment you notice a negative loop

Practical Tips

• Before the race, write 1–2 core motivational phrases on your wrist or race bib so you don’t have to memorize them
• Learn from fellow runners’ self-talk strategies, but convert them into your own way of speaking—borrowed phrases are less effective
• The comment sections on the running community Strava are a great place to record which phrases you used during tough workouts and how well they worked
• Consider working with a sports psychology consultant (certified by the Taiwan Society of Sport and Exercise Psychology) for one-on-one script design

Conclusion

Positive self-talk isn’t about telling yourself you’re not tired—of course you’re tired, it’s a marathon. Its purpose is to insert a buffer zone between “being tired” and “giving up,” giving you the chance to choose to keep going.

The next time you hear yourself say “I can’t go on” on Ren’ai Road or Guangfu South Road, remember: that’s just your brain sending a text message. You don’t have to accept it as is—you can choose to reply with a different message. “Thanks for the heads-up, but I choose to keep running.”
