Cycling power zones are essential for cyclists to improve performance and optimize training. Power-based training focuses on measuring the work done on the bike, quantified in watts. This method is gaining traction among cyclists because it allows for more precise training than traditional metrics like heart rate. Here’s a comprehensive overview of cycling power, its significance, and how to effectively implement power-based training in your routine.

Understanding cycling power zones?
At its core, cycling power, which is a key component in understanding cycling power zones, refers to the amount of work you are generating while pedaling, measured in watts. This measurement combines the force applied to the pedals (torque) and your pedaling speed (cadence).

To accurately track power output, which is key for defining your cycling power zones, cyclists typically use power meters. These meters can be installed in hubs, pedals, or cranks. Many smart trainers and indoor cycling bikes also come equipped with power measurement capabilities, allowing cyclists to monitor their output in real time and understand their cycling power zones.
Why do cycling power zones matter for training?
Power is a crucial metric in cycling because it provides an objective measure of effort. Unlike heart rate, which can fluctuate due to various factors such as stress or temperature, power output remains constant, offering a more reliable indicator of performance. As Vincent Murakami, a leading figure in the field of power-based training, explains, measuring power provides a clearer picture of performance.

This measurement allows cyclists to define their cycling power zones, which are specific power ranges that correspond to different training intensities. By focusing on power output and training within these defined cycling power zones, cyclists can tailor workouts to improve specific areas of fitness, leading to more effective training outcomes.
Understanding cycling power zones for training
Cycling training zones are categorized based on functional threshold power (FTP), which is the maximum power you can sustain for about an hour. These zones help cyclists structure their training sessions effectively. For instance, a long endurance ride might focus on zone 2, while an interval workout could target zone 4, which is closer to your threshold.

Here is a simplified breakdown of the common power zones:
- Zone 1 (Active Recovery): 0-55% of FTP
- Zone 2 (Endurance): 56-75% of FTP
- Zone 3 (Tempo): 76-90% of FTP
- Zone 4 (Lactate Threshold): 91-105% of FTP
- Zone 5 (VO2 Max): 106-120% of FTP
- Zone 6 (Anaerobic Capacity): 121-150% of FTP
- Zone 7 (Neuromuscular Power): 151% and above of FTP
By working within these zones, cyclists can focus on specific physiological adaptations, whether it’s building endurance, improving speed, or enhancing recovery.
How to set your cycling power zones
To establish your cycling power zones, you first need to determine your Functional Threshold Power (FTP). This can be done through various testing methods, with the 20-minute test being one of the most popular. After a proper warm-up, you’ll ride as hard as possible for 20 minutes. At the end, multiply your average power for that duration by 0.95 to estimate your FTP, which you will use to then calculate your cycling power zones.

Once your FTP is established, you can calculate your power zones based on the percentages outlined above. Many training apps can automate this process once you input your FTP.
How often should you retest your FTP?
Your FTP can change over time due to improvements in fitness or other factors. It’s advisable to retest your FTP every four to six weeks, especially if you are a beginner. For more experienced cyclists, retesting should align with your training cycles and goals. If workouts start feeling easier or harder than expected, it might be time for another test.
Using cycling power zones in your training

Once you have your power zones set, you can integrate them into your training. Most training plans will specify the duration and intensity for each workout, allowing you to monitor your power output during rides. Remember, the power levels are guidelines, not strict rules. Feel free to adjust based on how your body feels, especially in variable outdoor conditions.
The bottom line: Using cycling power zones effectively
Cycling power zones represent a powerful tool for cyclists looking to enhance their training. By focusing on measurable outputs, cyclists can refine their workouts to maximize performance gains. While it may seem complex at first, understanding and utilizing power zones can lead to more effective and enjoyable cycling experiences. Whether you’re a beginner or an experienced rider, power-based training can help you reach your cycling goals more efficiently.
