Cycling Training Zone Calculator | Power (FTP) & HR Zones

Smart Training for Every Cyclist

Unlock structured improvement in your cycling with our free Cycling Training Zones Calculator. This essential tool defines your personal cycling training zones from your training data. Whether you track power or heart rate, it helps establish a tailored approach to your cycling training zones.

What It Offers:

  • Power and Heart Rate Zones: This tool functions as a power output calculator to set your power zones (using FTP). It also defines your heart rate zones for cycling training, giving you complete metrics for your cycling training zones.
  • Complete Zone Breakdown: See all 7 power zones and 5 levels of heart rate training zones for cycling. You'll get simple guides for customizable intensity levels based on your cycling goals.
  • Instant Results: Get your cycling training zones right away to plan your next ride. No personal information is required to use the calculator.
  • Based on Science: Uses proven training ideas that professional cyclists use to define their training zones for cycling. Knowing your training zones is ideal for athletes interested in performance monitoring and workout tracking.

Why Use Training Zones?

Using the right cycling training zones is key to structured improvement, moving beyond random riding. Our calculator provides clarity, with your cycling training zones explained in a practical way. It shows how to use consistent power (watts) for reliable training—a steady measure heart rate alone can't always match.

When you understand your specific training zones your goals becomes more targeted. Build endurance in Zones 1-2, improve sustained efforts in Zone 4, or boost sprint power in Zones 6-7. This targeted approach to your cycling training zones removes guesswork, ensuring you train effectively.

Great for All Cyclists

Our cycling training zones calculator is helpful for any cyclist. It doesn't matter if you're checking your power on local hills or getting ready for a race. It helps you:

  • Avoid Overtraining: Train in the right cycling training zones to balance hard work with proper rest.
  • Train Smarter: Focus your efforts using insights from your personal cycling training zones to get the most out of each ride.
  • See Your Progress: Watch your cycling power get better over time by consistently using your zones.
  • Plan Your Rides: Create goal-oriented training plans using your personal cycling training zones.

Stop guessing. Calculate your cycling training zones today and start training with purpose and a clear plan.

⚙️ Training Targets

Watts
Your 1-hour maximum sustainable power output.

🎯 Key Training Targets

Zone 2 (Endurance)
140 - 188 W
Aerobic Base Building
Sweet Spot
210 - 235 W
84% - 94% FTP
Threshold (Zone 4)
228 - 263 W
Hour Race Pace
VO2 Max (Zone 5)
265 - 300 W
3-5 Min Intervals

💡 Pro Tip: Spend 75–80% of your weekly volume in Zone 2 to expand mitochondrial density and fat metabolism, reserving 15–20% for high-intensity intervals.

⚡ Understanding the 7 Cycling Power Zones (Coggan System) +

Dr. Andrew Coggan developed the 7-zone system to categorize how hard your body is working relative to your FTP (Functional Threshold Power):

  • Zone 1 (Active Recovery, <55% FTP): Easy pedaling. Keeps blood flowing to flush fatigue without adding training stress.
  • Zone 2 (Endurance, 56–75% FTP): All-day conversation pace. Builds your aerobic base, increases capillary density, and trains your body to burn fat for fuel.
  • Zone 3 (Tempo, 76–90% FTP): Brisk, spirited riding. Requires concentration; you can speak in short sentences.
  • Sweet Spot (84–97% FTP): The highest training stimulus per minute of fatigue. Bridges upper Tempo and lower Threshold.
  • Zone 4 (Lactate Threshold, 91–105% FTP): Hard work. This is your 1-hour maximum sustainable pace. Increases your ability to tolerate lactate.
  • Zone 5 (VO2 Max, 106–120% FTP): 3-to-5 minute hard intervals. Heavy gasping breath, elevates your maximum aerobic ceiling.
  • Zone 6 (Anaerobic Capacity, 121–150% FTP): 30-second to 2-minute steep punchy climb efforts.
  • Zone 7 (Neuromuscular, >150% FTP): Maximum 5-to-15 second explosive sprints.
❤️ Heart Rate Training: LTHR vs. Max Heart Rate Explained +

Why LTHR is Better Than Age Formulas: Generic formulas like "220 minus your age" have up to a ±15 bpm margin of error. Testing your Lactate Threshold Heart Rate (LTHR) establishes zones based on your real physiology.

Using the Karvonen Method: If you know your Resting Heart Rate (measured upon waking), the Karvonen formula uses your Heart Rate Reserve (Max HR - Resting HR) to give more personalized zones than simple percentage of Max HR.

⏱️ How to Accurately Test Your FTP and LTHR +

The 20-Minute Protocol:

  1. Warm up thoroughly for 15–20 minutes with a few 1-minute openers.
  2. Perform a 5-minute all-out effort to deplete anaerobic energy.
  3. Spin easy for 10 minutes.
  4. Ride at your absolute maximum sustainable pace for 20 minutes.
  5. Your FTP = 95% of your 20-minute average power.
  6. Your LTHR = Your average heart rate during the final 20 minutes.
