If you spend enough time in cycling communities, you will eventually see one number mentioned again and again:

FTP.

Professional cyclists talk about it. Indoor training platforms use it. Cyclists compare their FTP numbers online.

But what exactly is FTP? Why does it matter? And do you really need to know your FTP if you're not racing?

The short answer:

FTP is one of the best ways to understand your cycling fitness because it measures your actual effort—not just your speed.

What Is FTP in Cycling?

FTP stands for Functional Threshold Power.

In simple terms:

FTP is the maximum average power (measured in watts) that a cyclist can theoretically sustain for about one hour.

Power is measured in watts (W).

Unlike speed, which changes depending on:

· Wind

· Road conditions

· Hills

· Tire choice

· Traffic

Power measures the actual work your body is producing.

For example:

Two riders might both ride at 30 km/h.

But:

· Rider A is riding downhill with a tailwind.

· Rider B is riding on flat roads into a strong wind.

Their speeds are identical, but their effort is completely different.

Power reveals the difference.

Why Is FTP Important for Cyclists?

1. FTP Shows Your True Fitness Level

Many cyclists use average speed to judge improvement. But speed can be misleading. A faster ride doesn't always mean you became stronger. Maybe:

The weather was better.

The route was flatter.

The wind helped.

FTP gives you a more consistent measurement.

If your FTP increases from:

200W → 240W

you know your ability to produce sustained power has improved.

2. FTP Helps Create Better Training Zones

One of the biggest advantages of knowing your FTP is that it allows you to train at the correct intensity.

Instead of guessing:"Am I riding too hard?" Or："Am I not pushing enough?" ，your FTP creates personalized training zones.

A common training structure looks like this:

 

Training zone	Percentage of FTP	Purpose
Recovery	<55%	Easy recovery rides
Endurance	56%-75%	Build aerobic fitness
Tempo	76%-90%	Improve sustained effort
Therehold	91%-105%	Improve FTP
Vo2 Max	106%-120%	Increase high-intensity capacity

This helps cyclists train smarter instead of simply riding harder.

How Do You Test Your FTP?

There are several ways to estimate FTP.

The 20-Minute FTP Test

One of the most common methods:

1. Warm up thoroughly.

2. Ride as hard as possible for 20 minutes.

3. Take your average power.

4. Multiply by 0.95.

Example:

20-minute average power:

250W

Estimated FTP:

250 × 0.95 = 237.5W

This provides a practical FTP estimate.

Ramp Test

Many indoor training platforms use ramp tests. The effort gradually increases until you can no longer continue.

Advantages:

· Shorter testing time

· Easier pacing

· Beginner-friendly

Long Outdoor Efforts

Experienced cyclists can also estimate FTP from longer sustained efforts outdoors.

For example:

· Long climbs

· Time trials

· Race efforts

What Is a Good FTP?

This is one of the most common questions cyclists ask.

The answer:

It depends.

FTP varies depending on:

· Body weight

· Training history

· Age

· Gender

· Cycling experience

A beginner cyclist may have an FTP around: 100–200W; A trained recreational cyclist: 200–300W; Competitive cyclists: 300W+; Professional riders: 400W+

However, comparing FTP numbers directly can be misleading.

A better measurement is:

FTP per kilogram (W/kg)

This compares power relative to body weight.

For example:

Cyclist A: 250W FTP, 100kg body weight = 2.5 W/kg

Cyclist B: 250W FTP, 70kg body weight = 3.6 W/kg

Same FTP.

Different performance potential.

How Can You Improve Your FTP?

Increasing FTP takes consistent training. The most effective methods include:

1. Build Your Aerobic Base

Long, easier rides improve your body's ability to use energy efficiently. Many cyclists use zone 2 training and longer endurance rides as the foundation of FTP improvement.

2. Add Threshold Intervals

Threshold training teaches your body to sustain higher power.

Examples:

2 × 20 minutes near FTP

3 × 10 minutes above endurance pace

These workouts are challenging but highly effective.

3. Improve Recovery

More training isn't always better. FTP improves when your body adapts after training.

Important factors:

Sleep

Nutrition

Rest days

Training consistency

4. Track Your Progress

Without measurement, it is difficult to know whether your training works.

Tracking:

Power

Heart rate

Training volume

Recovery

helps you understand your progress over time.

FTP vs Heart Rate: Which One Should You Use?

Many cyclists ask: "Should I train with heart rate or power?"

The answer depends on your goals.

Heart Rate

Advantages:

· Affordable

· Easy to understand

· Good for beginners

Limitations:

Heart rate changes because of:

· Heat

· Stress

· Fatigue

· Caffeine

· Sleep quality

Power

Advantages:

· Measures actual output

· Immediate response

· More accurate for structured training

Limitations:

· Requires a power meter

· Requires understanding training zones

Many serious cyclists use both:

Power tells you how hard you are working.

Heart rate tells you how your body is responding.

Why More Cyclists Are Using Power Meters

Power meters were once considered equipment only for professional cyclists. Today, they are becoming much more accessible.

More riders use power data because it helps answer important questions:

· Am I improving?

· Am I training at the right intensity?

· Why am I slower today?

· How much effort did that climb really take?

Instead of relying only on speed, cyclists can now understand their actual performance.

How a Cycling Computer Helps With FTP Training

FTP training requires consistent tracking. A cycling computer allows riders to monitor:

Current power

Average power

Heart rate

Training zones

Workout data

During structured workouts, real-time data helps you stay within the correct intensity range.

For example:

During an FTP interval, a cyclist can immediately see whether they are:

Below target power

Riding too hard

Maintaining the correct effort

Using a Power Meter for Smarter Training

A power meter such as Coospo S10 Power Meter allows cyclists to measure their real output during every ride.

Combined with a GPS bike computer like Coospo CS600, riders can view important training data including:

· Power output

· Heart rate

· Speed

· Cadence

· Ride history

This allows cyclists to move from: "I think I trained hard today." to: "I completed my target training session."

Final Thoughts

FTP is more than just a number cyclists compare online. It is a tool that helps riders understand their fitness, structure training, and measure progress.

Whether you're preparing for your first race, improving your endurance, or simply trying to become a stronger cyclist, understanding FTP can help you train with more purpose. You don't need to chase professional-level numbers.

The most important FTP is your own:

The number that shows you are becoming stronger than yesterday.

FAQ

What does FTP mean in cycling?

FTP stands for Functional Threshold Power. It represents the maximum sustainable power a cyclist can maintain for approximately one hour.

Do beginners need to know their FTP?

Beginners don't need FTP immediately, but it becomes increasingly useful when starting structured training.

Is a higher FTP always better?

A higher FTP generally indicates stronger performance, but FTP relative to body weight (W/kg) is often more meaningful.

Can I improve FTP without a power meter?

Yes, but a power meter makes training more accurate and allows better progress tracking.
