Does Stopping During Training Make You a Worse Athlete? What the Science Actually Says

“I didn’t stop once.”

For many endurance athletes, that’s worn as a badge of honour.

No café stop.

No bottle refill.

No sitting down.

No pause.

Somewhere along the way, we’ve created the idea that if you stop during a ride or run, the session somehow doesn’t count.

But where did that belief come from?

And more importantly, does the science support it?

The answer is no.

In fact, much of the research points in the opposite direction: athletes often overestimate how quickly fitness disappears while underestimating the importance of fuelling, recovery and consistency.

Why do we feel guilty for stopping?

In many sports, breaks are completely normal.

• Tennis has changeovers.
• Cricket has drinks breaks.
• Football and rugby have half-time and substitutions.
• Marathon and ultramarathon races have aid stations.
• Cycling sportives and races often include feed zones.

Yet many recreational athletes feel guilty pulling over to refill bottles or eat.

Why?

Because we’ve linked stopping with weakness.

We’ve confused suffering with effective training.

But physiology doesn’t work like social media.

Your muscles don’t know whether you ate while rolling or standing next to your bike.

They care whether they received enough carbohydrate, fluid and energy to support the work you’re asking them to do.

Fitness isn’t as fragile as you think

One of the biggest fears athletes have is:

“If I stop, I’ll lose fitness.”

Research suggests otherwise.

Study 1: Reduced training for 21 days

Rietjens and colleagues (2001) investigated what happened when well-trained cyclists reduced both training volume and intensity for 21 days.

Despite training less, cyclists maintained:

• VO₂max
• Maximal power output
• Heart rate responses
• Submaximal physiological adaptations

In other words, three weeks of reduced training did not impair cycling performance.

This is important because athletes often panic about tiny interruptions:

• stopping for coffee
• taking an easier week
• missing one session
• shortening a ride

The evidence suggests our bodies are far more resilient than our minds believe.

Study 2: Six weeks without strength training

Another study by Bláfoss et al. (2022) looked at competitive cyclists who completed:

• 8 weeks of strength training alongside cycling
• followed by 6 weeks of cycling only before competition

After stopping resistance training for six weeks, cyclists retained:

• maximal strength
• cycling performance
• performance gains achieved during the strength block

The researchers concluded cyclists could focus on cycling leading into races without immediately losing the adaptations they’d built.

Again, this tells us something important:

Performance doesn’t disappear overnight.

What actually determines adaptation?

Training adaptations occur because of repeated stress followed by adequate recovery.

Not because you refused to stop your Garmin.

Stopping briefly to eat doesn’t erase:

• mitochondrial adaptations
• cardiovascular adaptations
• muscular adaptations

Those changes occur over weeks and months of consistent training.

What does affect adaptation?

Much more important than a two-minute café stop is whether you’re consistently under-fuelling.

Low carbohydrate availability can reduce:

• training quality
• power output
• recovery
• immune function

Repeated low energy availability can contribute to:

Relative Energy Deficiency in Sport (RED-S)

• impaired bone health
• hormonal disruption
• increased injury risk
• reduced performance

Ironically, avoiding stops to “look tough” may do more harm than stopping ever could.

Context changes everything

Your nutritional needs are never identical from one session to the next.

Think about everything your body is already managing:

• work stress
• family responsibilities
• exams
• poor sleep
• menstrual cycle changes
• illness
• heat
• altitude
• cumulative training fatigue

All of these increase physiological stress.

The ride might look the same on your training plan.

Your body isn’t.

Why I plan fuelling stops

One thing that completely changed my riding was planning fuelling before I needed it.

Instead of waiting until I felt empty, I’d already know where I’d refill bottles or eat.

Because once you bonk, recovery during that ride becomes much harder.

A two-minute stop early can prevent an hour of struggling later.

That’s not weakness.

That’s good decision making.

Better questions to ask yourself

Instead of asking:

• Did I stop?
• How fast was I?
• Did I suffer enough?

Try asking:

• Will this pace and fuelling allow me to recover well?
• Will I have enough energy for work and family afterwards?
• Can I train well again tomorrow?
• Am I fuelling because my body needs it, or avoiding fuelling because of my ego?

These questions are far more predictive of long-term performance than whether your average speed was 0.3 km/h faster.

The best athletes aren’t those who never stop.

They’re the ones who know when stopping improves the outcome.

Sometimes that’s to refill bottles.

Sometimes it’s to eat.

Sometimes it’s because today’s life stress means the body needs more.

Training should improve your life—not leave you unable to enjoy it.

At RED-Scue, that’s exactly why we created our Energy Bars.

They’re designed to make fuelling simple, gut-friendly and easy to carry, so stopping to fuel feels like part of training—not a sign you’ve failed.

Because a session doesn’t count because you never stopped.

It counts because you trained in a way that lets you come back tomorrow and do it again.
