For competitive swimmers, few achievements are celebrated more than achieving a PB. You'll often hear coaches, swimmers and parents talking about PBs at training, poolside and after competitions.

But what exactly is a PB, and why is it so important?

Whether you're new to competitive swimming or supporting a swimmer through their journey, this guide explains everything you need to know about Personal Bests (PBs), why they matter, and why coaches often encourage swimmers to focus on the process rather than just the stopwatch.

What Does PB Mean in Swimming?

PB stands for Personal Best.

A Personal Best is the fastest time a swimmer has achieved in a particular event.

For example:

• 50m Freestyle – 34.20 seconds
• 100m Freestyle – 1:15.40
• 200m Individual Medley – 2:58.30

Each event has its own PB.

A swimmer could achieve a PB in one event while swimming slower than usual in another during the same competition.

---

Why Are PBs So Important?

Swimming is unique because success isn't always measured by winning races.

Unlike many sports, swimmers compete against both:

• Other swimmers
• Their own previous performances

A swimmer who finishes sixth but achieves a new PB may have had a more successful race than someone who wins but swims slower than their usual standard.

PBs allow swimmers to:

✅ Measure improvement

✅ Track long-term development

✅ Set realistic goals

✅ Build confidence

✅ Stay motivated

For many coaches, improvement is often more important than medals, particularly for younger swimmers.

While PBs are an excellent way of measuring progress, coaches often encourage swimmers to focus on the process rather than the outcome. The process includes attending training consistently, improving technique, practising race skills, listening to feedback and developing healthy habits. When swimmers commit to the process, PBs often follow naturally over time.

---

How Are PBs Recorded?

PBs are usually recorded from official competition results.

After each race, a swimmer's time is published and compared with their previous best.

For example:

Many swimming clubs and ranking websites automatically track PBs throughout a swimmer's competitive career.

---

What Is a Good PB Improvement?

This is one of the most common questions parents ask.

The answer depends on several factors:

• Age
• Experience level
• Event distance
• Training volume
• Stage of development

New swimmers often make large improvements because they are developing skills quickly.

Experienced swimmers may celebrate improvements of:

• 0.50 seconds
• 0.20 seconds
• 0.10 seconds

At higher levels of swimming, tiny improvements can make a huge difference.

For elite swimmers, even a hundredth of a second can separate medal positions.

---

Why Do PBs Become Harder to Achieve?

Early in a swimmer's journey, PBs often happen frequently.

As swimmers develop, improvements become harder because:

• Technique improves
• Fitness increases
• Efficiency gets better
• Times approach current potential

Think of it like climbing a mountain.

The first part of the climb may feel quick, but progress becomes slower and more challenging as swimmers get closer to their potential.

This is completely normal and part of athlete development.

---

Why Might a Swimmer Not Get a PB?

Many swimmers and parents feel disappointed when a PB isn't achieved.

However, not every race needs to produce a PB to be successful.

A swimmer may still gain valuable experience by:

• Racing stronger competitors
• Learning race tactics
• Improving turns
• Perfecting starts
• Developing confidence
• Managing race-day nerves

This is where coaches often talk about trusting the process.

Sometimes swimmers are working on technical changes that may initially make them slower in competition. A coach may be focusing on:

• Better streamlining
• Improved underwater work
• More efficient turns
• Stroke technique adjustments
• Improved race pacing

These changes may take weeks or even months to become natural. During this period, PBs may not happen as frequently, but the swimmer is still progressing through the process of becoming a better athlete.

Progress in swimming is rarely a straight line. Swimmers may appear to plateau for a period before making a significant breakthrough. Those who stay committed to the process often see the biggest long-term improvements.

---

What Is a PB Percentage?

Coaches sometimes look beyond the actual time and analyse the percentage of improvement.

For example:

Previous PB: 1:20.00

New Time: 1:18.80

Improvement: 1.20 seconds

Percentage Improvement: 1.5%

Tracking percentages can help coaches compare progress across different events and distances.

---

Short Course and Long Course PBs

You may hear swimmers talk about:

Short Course (SC)

A 25-metre pool.

Long Course (LC)

A 50-metre pool.

Swimmers keep separate PBs for each pool type because racing conditions are different.

A swimmer may therefore have:

• Short Course 100m Freestyle PB
• Long Course 100m Freestyle PB

Both are recognised and important.

How Swimmers Can Improve Their PBs

The most successful swimmers understand that great performances come from focusing on the process every day.

Regular Training

Attending sessions consistently allows swimmers to improve technique, fitness and race skills over time.

Listening to Coaches

Small technical improvements are often the foundation of future PBs. Sometimes swimmers need patience while new skills become second nature.

Good Nutrition

Fueling the body properly supports recovery and performance.

Quality Sleep

Recovery is a crucial part of the training process.

Positive Mindset

Swimmers who focus on executing race plans rather than chasing times often perform more consistently.

The process is about controlling the things you can control. Swimmers cannot guarantee a PB every time they race, but they can control their preparation, effort, attitude and commitment.

---

Trust the Process

One phrase swimmers hear regularly from coaches is:

"Trust the process."

This means focusing on the daily habits that lead to improvement rather than becoming fixated on immediate results.

The process includes:

✅ Attending training consistently

✅ Working hard during sets

✅ Listening to coaching feedback

✅ Improving technique

✅ Eating well

✅ Sleeping properly

✅ Supporting teammates

✅ Staying positive at competitions

Every successful swimmer experiences periods where PBs seem difficult to achieve. This doesn't mean progress has stopped.

Often, swimmers are building the foundations for future success through technical improvements, physical development and race experience. These gains may not always show up immediately on a results sheet, but they are still important parts of the process.

The swimmers who achieve long-term success are usually those who learn to enjoy the process, not just the outcome.

PB Myths

Myth 1: A Race Is Only Successful If It's a PB

False.

Many successful races involve gaining experience, improving technique, practising race skills or achieving competition goals.

Myth 2: Faster Swimmers Get More PBs

False.

All swimmers eventually reach stages where improvements become smaller and harder to achieve.

Myth 3: Missing a PB Means Something Went Wrong

False.

Swimming performance is affected by many factors including training load, recovery, growth, illness, competition experience and race strategy.

Should Parents Focus on PBs?

The simple answer is: yes, but not exclusively.

Parents should celebrate:

✅ New PBs

✅ Improved technique

✅ Positive attitude

✅ Race skills

✅ Effort

✅ Confidence

✅ Commitment to training

A swimmer who hasn't achieved a PB may still have made enormous progress in other areas.

One of the best things parents can do is reinforce the importance of the process. Ask questions such as:

• Did you execute your race plan?
• Did you improve your turns?
• Did you give your best effort?
• What did you learn?

These conversations help swimmers develop a healthy long-term approach to sport.

---

How Coaches Use PBs

PBs help coaches:

• Measure progress
• Set goals
• Plan training programmes
• Monitor development
• Identify strengths
• Identify areas for improvement

However, coaches rarely look at PBs in isolation.

A swimmer's attitude, commitment, technique, race execution and consistency are all valuable indicators of progress. This is why coaches often place as much emphasis on the process as they do on the final time.

Frequently Asked Questions

What does PB stand for in swimming?

PB stands for Personal Best, which is the fastest time a swimmer has achieved in a particular event.

Can swimmers get a PB in every race?

No. As swimmers improve, PBs become harder to achieve consistently.

Are PBs different in 25m and 50m pools?

Yes. Short Course and Long Course PBs are recorded separately.

Is a swimmer unsuccessful if they don't get a PB?

Absolutely not. Progress can be measured through technique, confidence, race skills and commitment to the process.

Why do coaches celebrate small PBs?

Because even the smallest improvement can represent weeks or months of hard work, training and dedication.

Final Thoughts

A Personal Best is much more than a number on a results sheet. It represents commitment, learning, perseverance and improvement. While medals and trophies are exciting, PBs are often one of the clearest signs that a swimmer is moving forward.

At the same time, coaches often remind swimmers that the ultimate goal is not simply to chase times. The real focus should be the process—attending training, improving technique, learning race skills, building confidence and developing resilience.

When swimmers trust the process and continue working consistently, PBs usually become a natural result of all the effort invested along the way.

After all, swimming is not about becoming the best overnight—it's about becoming a little better every day. 🏊♂️🏊♀️💙
