Performance Anxiety in Endurance Sports: What’s Happening & What to Do About It

You’ve put in the training. You’ve done the work. So why does race day sometimes feel like it’s working against you?

For many endurance athletes, the missing piece isn’t fitness or nutrition — it’s what’s happening between the ears. In this free live session, mental performance expert Carrie Jackson, M.A., CMPC breaks down the psychobiology of performance anxiety and shares tools you can start using right now.

## Why Endurance Athletes Are Especially Vulnerable

Performance anxiety isn’t unique to endurance sports — but the stakes are different here. A soccer player who has a rough game can try again next week. You’ve spent months building toward a single day. That weight is real, and it’s one reason why race-day nerves hit harder in endurance sport.

Carrie identifies the main contributors to pre-race anxiety:

– The outcome matters deeply to you

– The situation is unfamiliar or unpredictable

– You’re putting internal pressure on yourself

– Training has shifted from “want to” to “have to”

What all of these have in common: your brain has interpreted the race as a threat. And once that happens, everything downstream changes.

## The Psychobiology: What Stress Actually Does to Your Body

When your nervous system perceives a threat, the physiological response is real and measurable:

– Increased heart rate — before you’ve run a single step

– Increased muscular tension — enough to interfere with motor skill execution

– Decreased flexibility, coordination, and balance

– Tunnel vision — reduced awareness of your surroundings

– Impaired decision-making — your rational brain goes offline

– Faster fatigue — you’re burning matches before the gun goes off

– Higher injury risk

The takeaway: mental training isn’t a “nice to have.” It’s a performance variable as real as your VO2 max.

## The Cognitive Appraisal Model: When a Stressor Becomes Stressful

A stressor — a demand placed on you — isn’t inherently stressful. It becomes stressful the moment you decide you can’t handle it. That perception of capacity vs. demand is everything, and it shapes your confidence, motivation, and race-day behavior from there.

## Self-Sabotage: The Hidden Race-Day Threat

When we perceive something as a threat, we sometimes unconsciously sabotage our own performance to create a built-in excuse for not doing well. Carrie shared the example of an elite ultra runner who agreed to race two weeks before an A-race — only realizing in conversation that the real reason was to have an out if the A-race didn’t go well.

Your brain is trying to protect you. Your job is to recognize it.

## 3 Tools You Can Use Right Now

### Tool 1: Weight of the World

Draw a stick figure of yourself at the bottom of a page. Above it, write down everything you’re carrying into race day — every source of pressure, every what-if, every expectation. Assign a weight in pounds to each item. Add them up.

Now imagine putting on that weight vest and racing. That’s what that pressure is doing to you.

The work: go through each item and ask, “What do I need to do to shave even 5–10 pounds off this?” You don’t need to reach zero. You just need a lighter load.

### Tool 2: What Am I Looking Forward To? + Evidence List

Write it down — pen to paper. What are you genuinely looking forward to? It doesn’t have to be race-related.

Then build your evidence list: Why am I ready for this? Your brain’s negativity bias will hunt for reasons things might go wrong. Counter it with documented proof that you’re prepared.

### Tool 3: The Pre-Performance Plan

For each critical moment in your race — the start, a hard climb, a transition, the final miles — define three things in advance:

1. The situation: What’s happening at this moment?

2. The emotion: How do I want to feel?

3. The self-talk: What do I need to say to myself to feel that way?

Do this ahead of time. Your brain isn’t burning bandwidth making decisions under pressure — you’ve already decided.

## Courage Over Confidence

Rory McIlroy — one of only four golfers to win back-to-back Masters titles — said something worth sitting with: “You have to be willing to get your heart broken.”

There was a period in his career when he wasn’t willing to put everything on the line. He saw it in his results. The shift wasn’t about building more confidence — it was about choosing courage. Until you’re willing to show up fully knowing it might not be enough, you’ll never know what you’re actually capable of.

## Bonus: The Pain Cave

Near the end of the session, the conversation turned to a concept many endurance athletes know well — the pain cave. Carrie described it as a perception issue as much as a physical one: your brain is wired to interpret pain as danger, which means endurance suffering often triggers a retreat response unless you’ve trained yourself to reframe it.

If you want to go deeper on that topic, Carrie has written about it previously on the TrainingPeaks blog:

It’s older but the concepts hold up — and Carrie hinted this might be the topic for a future 80/20 live session.
