1. What is the British Cycling Power Calculator?

The British Cycling Power Calculator estimates cycling power output based on Functional Threshold Power (FTP) and effort level. It helps cyclists understand their power output at different effort levels during training or competition.

2. How Does the Calculator Work?

The calculator uses the power equation:

Where:

• \( FTP \) — Functional Threshold Power in watts
• \( Effort\_Level \) — Dimensionless multiplier representing effort intensity

Explanation: The equation calculates power output by multiplying your FTP by your current effort level (e.g., 0.7 for endurance, 1.0 for threshold, 1.2 for VO2 max efforts).

3. Importance of Power Calculation

Details: Power measurement is crucial for training intensity control, performance tracking, and race strategy in cycling.

4. Using the Calculator

Tips: Enter your FTP (from a recent test) and effort level (typically 0.5-1.5). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is FTP?
A: Functional Threshold Power is the highest power you can sustain for approximately one hour, measured in watts.

Q2: What are typical effort levels?
A: 0.5-0.7 for endurance, 0.8-0.9 for tempo, 1.0 for threshold, 1.1-1.3 for VO2 max, 1.5+ for anaerobic efforts.

Q3: How often should I test my FTP?
A: Every 4-6 weeks for most cyclists, or whenever your fitness level changes significantly.

Q4: Does this account for fatigue?
A: No, this is a simple calculation. Actual power may vary based on fatigue, nutrition, and other factors.

Q5: Can I use this for power zone training?
A: Yes, this can help estimate power outputs for different training zones based on your FTP.
