1. What is British Cycling HR Zone?

The British Cycling Heart Rate Zone system divides your heart rate range into five zones to help cyclists train at the right intensity for their goals. This method is widely used in cycling training programs.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• HRR — Heart Rate Reserve (Max HR - Resting HR)
• Intensity — Percentage of effort (60-100%)
• RHR — Resting Heart Rate

Explanation: The formula calculates training zones based on your personal heart rate range between resting and maximum.

3. Importance of HR Zones

Details: Training in specific heart rate zones helps optimize workouts for different goals like endurance, fat burning, or speed improvement.

4. Using the Calculator

Tips: For best results, measure your true maximum heart rate with a field test. Resting HR should be measured first thing in the morning before getting out of bed.

5. Frequently Asked Questions (FAQ)

Q1: How accurate are these zones?
A: They provide a good estimate, but for maximum accuracy consider a lab test to determine your exact thresholds.

Q2: What's the best way to measure max HR?
A: The most accurate method is a supervised stress test, but a field test (like a 3-minute all-out hill climb) can provide a good estimate.

Q3: Do these zones change with fitness?
A: Yes, as your fitness improves, your resting HR may decrease, which could slightly adjust your zones.

Q4: Are these zones only for cycling?
A: While designed for cycling, they can be adapted for other endurance sports with similar cardiovascular demands.

Q5: How often should I retest my max HR?
A: Typically once or twice a year, as max HR tends to decrease slowly with age.
