Key Takeaways

  • Cycling heart rate zones are 5–10 bpm lower than running zones at the same effort level due to the seated position and less upper-body recruitment.[1]
  • Four zone methods available: age-based %MaxHR, Karvonen heart rate reserve, LTHR-based (Friel/Coggan), and Zoladz fixed subtractions.[2]
  • Both 5-zone and 7-zone (Coggan) systems are supported — the 7-zone model adds sweet spot, VO2max, and anaerobic sub-zones for advanced training.[3]
  • A 30-minute cycling time trial provides the most accurate LTHR for zone calculation — formula-based methods are useful starting estimates.

Why Cycling Needs Its Own Heart Rate Zones

Heart rate response differs between cycling and running due to biomechanical and positional factors. Cycling is performed in a seated position with less gravitational demand, which means lower heart rate output at equivalent effort levels. Research shows cycling max HR is typically 5–10 bpm lower than running max HR for the same individual.[1]

Using running-derived heart rate zones for cycling leads to zones that are too high, causing misinterpretation of training intensity. This calculator applies a cycling-specific offset to ensure your zones match your actual cycling physiology. If you also run, compare your zones with our Heart Rate Zone Calculator or Karvonen Heart Rate Calculator.

Four Zone Calculation Methods

1. Age-Based %MaxHR

Uses the Tanaka formula (MaxHR = 208 − 0.7 × age), which is more accurate than the outdated 220 − age formula.[2] Zones are built as percentages of max HR with the cycling offset applied. Simplest method but least individualized.

2. Karvonen (Heart Rate Reserve)

Accounts for resting heart rate, making zones more personalized. Two cyclists the same age with different resting HRs will get different zone boundaries. Requires knowing your morning resting HR.[3]

3. LTHR-Based (Friel/Coggan)

The gold standard for cycling zones. Perform a 30-minute all-out cycling effort, then use your average HR from the last 20 minutes as your LTHR. Zones are built as percentages of this value. This approach powers the Coggan 7-zone model used by most cycling coaches.

4. Zoladz Method

Uses fixed bpm subtractions from your max HR (e.g., Zone 1 = MaxHR − 50 to MaxHR − 40). Simple and intuitive, but does not account for individual fitness levels. Useful for riders who prefer straightforward numeric boundaries.

5-Zone vs. 7-Zone System

The 5-zone system groups training into Recovery, Endurance, Tempo, Threshold, and VO2max. It covers the full intensity spectrum and is straightforward for most riders.

The 7-zone (Coggan) systemsplits Zone 4 into “Sweet Spot” and “Threshold” and splits Zone 5 into “VO2max” and “Anaerobic Capacity.” This added granularity helps athletes fine-tune intervals and track progression in specific intensity bands.

If you also train with a power meter, pair your HR zones with our Cycling Power Zones Calculator for complementary data.

Understanding the Cycling HR Offset

The offset adjusts for the well-documented difference between cycling and running max HR. The primary reasons for this difference:[1]

  • Seated position: Less gravitational load on the body compared to upright running, resulting in a lower heart rate at the same effort.
  • Less muscle mass engaged: Cycling primarily uses the lower body, while running recruits more upper-body stabilizers, driving a higher overall heart rate response.
  • Airflow cooling: Moving air while cycling helps dissipate heat, reducing the need for the body to elevate heart rate for thermoregulation.

A 5 bpm offset is a good default. Competitive cyclists with cycling-specific max HR tests may use 0 if their known max HR was tested on a bike. For those who also track running zones, see our Anaerobic Threshold HR Calculator.

How to Use This Calculator

  1. Select a method: Start with age-based for a quick estimate, or LTHR-based if you've done a time trial.
  2. Choose 5-zone or 7-zone: 5-zone is simpler; 7-zone provides more granularity for structured training.
  3. Set the cycling offset: Default is 5 bpm. Set to 0 if your known max HR was tested on a bike.
  4. Enter your data: Age is always required. Add resting HR for Karvonen, or LTHR for the Friel method.
  5. Train by zones: Keep 80% of ride time in Zones 1–2, with structured efforts in higher zones 1–2 times per week.
