Functional Threshold Power (FTP) is one of the most important metrics used by cyclists to measure performance and guide their training. It helps riders assess their ability to maintain a high level of power output over a sustained period, usually measured over an hour. But what exactly is a “good” FTP for cycling? This article breaks it down and explains how to interpret and improve your FTP.
What Is FTP?
FTP stands for Functional Threshold Power, which refers to the maximum average power a cyclist can sustain for about one hour without fatiguing. Measured in watts, FTP provides a benchmark for your cycling performance, allowing you to compare your abilities against others and track your progress over time.
FTP is often used as a cornerstone of training, helping cyclists set workout zones, monitor improvements, and plan races. Many cyclists use power meters to track FTP, as they offer accurate real-time measurements of power output.
Why Is FTP Important?
FTP is an essential measurement for cyclists because it reflects your endurance and power output capacity. It helps answer the question, “How long can I maintain a strong effort before fatigue sets in?” Whether you’re a professional racer or an amateur, FTP can provide insights into your strengths and weaknesses on the bike.
Training Zones: FTP helps define your power training zones. Each zone targets different energy systems, allowing cyclists to train more effectively for endurance, sprints, or climbs.
Race Strategy: Understanding your FTP helps with pacing during races or time trials. Knowing how hard you can push for sustained periods without burning out can be the difference between finishing strong or fading early.
Tracking Progress: Since FTP improves with training, it serves as a key metric to gauge improvements in your fitness and power output over time.

What Is a Good FTP for Cycling?
The idea of a “good” FTP varies depending on factors such as age, gender, experience, and goals. There is no single answer, but we can offer some guidelines to help you understand where your FTP stands.
FTP Relative to Body Weight
A common way to evaluate FTP is to look at watts per kilogram (W/kg), which adjusts your power output for your body weight. This gives a better comparison between cyclists of different sizes. For example, a 75kg rider with an FTP of 300 watts has an FTP of 4 W/kg, while a 60kg rider with the same 300 watts would have an FTP of 5 W/kg.
General FTP Ranges Based on Fitness Level:
- Beginner Cyclist: 2.0 – 2.5 W/kg
- Intermediate Cyclist: 2.5 – 3.5 W/kg
- Advanced Cyclist: 3.5 – 4.5 W/kg
- Elite/Pro Cyclist: 4.5 W/kg and above
So, if you’re a beginner and your FTP is around 2.5 W/kg, you’re on the right track. Advanced riders might aim for an FTP in the range of 4 W/kg, while elite riders push beyond 5 W/kg.
Absolute FTP Values
For cyclists who prefer to focus on absolute FTP numbers rather than W/kg, here are some rough benchmarks based on your overall fitness:
Beginner (Recreational Cyclist): 150-200 watts
Intermediate (Club Rider): 200-250 watts
Advanced (Competitive Amateur): 250-300 watts
Elite (Professional Cyclist): 300 watts and above
These numbers can vary significantly based on age, gender, and training history, but they offer a general idea of what to expect at different levels of cycling.
Factors That Affect FTP
Several factors influence a cyclist’s FTP, including genetics, training, nutrition, and body composition. Here’s a breakdown of the key elements:
Genetics
Genetics play a major role in determining your potential FTP. Some people naturally have a higher aerobic capacity, while others may have to work harder to increase their power output. However, training can significantly improve FTP, even for those without natural advantages.
Training
FTP responds well to structured, consistent training. Riders who focus on improving their aerobic endurance, leg strength, and overall fitness see significant gains in their FTP over time. Interval training, tempo rides, and long endurance rides are common methods used to increase FTP.
Nutrition and Hydration
Proper nutrition and hydration are crucial to maximizing your FTP. Carbohydrates fuel high-intensity efforts, while hydration ensures optimal muscle function. Inadequate fueling or dehydration during long rides can result in a drop in power output.
Body Weight
Cyclists with a leaner body composition tend to have higher W/kg FTP values, especially when climbing hills. However, losing weight while maintaining power output requires a delicate balance of diet and training, as losing too much weight can lead to muscle loss and reduced strength.
How to Test Your FTP
Testing your FTP is essential for setting up training zones and tracking your progress. There are two common methods for testing your FTP:
1. 20-Minute FTP Test
One of the most popular methods is the 20-minute test, where you ride as hard as you can for 20 minutes. Your average power output over this period is then multiplied by 0.95 to estimate your FTP. For example, if your average power over 20 minutes is 250 watts, your FTP would be approximately 238 watts (250 x 0.95).
2. 60-Minute FTP Test
The 60-minute test involves riding at your maximum sustainable effort for a full hour. This test is considered the gold standard for determining FTP, as it directly measures your one-hour power capacity. However, it is physically and mentally demanding, which is why the 20-minute test is often preferred.
How to Improve Your FTP
Improving your FTP requires consistent, structured training and attention to detail. Here are several key strategies for increasing your FTP:
1. Interval Training
High-intensity interval training (HIIT) is one of the most effective ways to boost your FTP. Interval sessions include short bursts of high-intensity efforts followed by rest periods. Over time, these efforts help your body become more efficient at producing power, improving your FTP.
For example, a typical interval session might include 5 x 5-minute efforts at 105-110% of your current FTP, with 5 minutes of recovery between each effort.
2. Threshold Training
Threshold training involves riding just below or at your FTP for sustained periods. This type of training improves your body’s ability to clear lactate from the muscles, allowing you to ride harder for longer. You might perform 2 x 20-minute efforts at 95-100% of FTP with a short rest between efforts.
3. Endurance Rides
Long, steady endurance rides build aerobic capacity and improve overall fitness, which in turn helps increase FTP. These rides are typically done at a moderate pace (60-70% of your FTP) for 2-5 hours, depending on your goals and experience level.
4. Strength Training
Strength training off the bike is another way to improve your cycling power. Squats, lunges, and leg presses can help build the muscle strength required to push higher power outputs.
5. Recovery
Rest is just as important as training when it comes to improving your FTP. Overtraining can lead to fatigue, injury, and burnout. Be sure to schedule rest days or lighter recovery rides into your weekly plan.
FTP and Different Types of Cycling
Your FTP might be more or less important depending on the type of cycling you do. Here’s how FTP affects different cycling disciplines:
Road Cycling
In road cycling, a higher FTP can help you sustain high speeds during time trials or breakaways. It also helps with climbing, allowing you to maintain strong efforts on long, steep ascents.
Mountain Biking
Mountain biking requires bursts of high power followed by recovery periods. While FTP is important for sustained climbs and long efforts, mountain bikers also need strong anaerobic power and technical skills.
Track Cycling
Track cyclists focus on shorter, more intense efforts, so FTP is less crucial than sprint power. However, it can still be beneficial for events like the pursuit or points race, where endurance plays a role.
Triathlon
For triathletes, FTP is a key factor in cycling performance, especially during longer events like Ironman races. A higher FTP allows you to maintain a steady pace on the bike without burning out before the run.
Conclusion
A good FTP for cycling depends on your goals, experience level, and body weight. Beginners might aim for 2.5 W/kg, while advanced riders strive for 4 W/kg or higher. By focusing on structured training, proper nutrition, and recovery, cyclists of all levels can work toward improving their FTP. Whether you’re a recreational rider or a competitive athlete, understanding and improving your FTP can make you a stronger, faster, and more efficient cyclist.
