Cycling Heart Rate Zones
Cycling-specific heart rate zone calculator. Train by intensity across endurance, tempo, threshold, and VO₂ max efforts using your personal HRmax.
Cycling HR Zones vs Running HR Zones
Cycling HR at any given perceived effort is typically 5–10 bpm lower than running HR at the same RPE. The seated position, lower muscle mass recruitment, and reduced venous return from the legs all suppress peak cardiac output. Athletes who use their running HRmax to set cycling zones consistently overshoot and end up training harder than intended.
Practical rule: either measure cycling HRmax with a dedicated bike test, or subtract ~8 bpm from your running HRmax and use that as the cycling reference.
HR vs Power — Why Serious Cyclists Use Both
Heart rate lags behind effort by 30–60 seconds and drifts upward over the course of a long ride (cardiac drift), so it is a poor tool for pacing short intervals. Power (watts) responds instantly and never drifts. Most structured cycling plans define zones in watts, then use HR as a secondary check on cumulative fatigue.
Sample Weekly Cycling Structure (8 hours)
- 2 × endurance rides (Zone 2, 90–120 min each) — aerobic base
- 1 × threshold session (Zone 4, 3–5 × 8–10 min, ~55 min total) — lactate clearance
- 1 × VO₂max session (Zone 5, 5 × 3 min hard / 3 min easy, ~45 min total) — top-end power
- 1 × long ride (Zone 2 with occasional Zone 3 climbs, 3–4 h) — durability
Heart Rate Zones (reference: age 30, HRmax ≈ 187 bpm, Tanaka)
| Zone |
Name |
% HRmax |
BPM (age 30) |
Primary use |
| 1 | Recovery | 50–60% | 94–112 | Warm-up, recovery, active rest |
| 2 | Endurance | 60–70% | 112–131 | Aerobic base, fat oxidation |
| 3 | Aerobic | 70–80% | 131–150 | Tempo, aerobic capacity |
| 4 | Threshold | 80–90% | 150–168 | Lactate threshold intervals |
| 5 | Maximum | 90–100% | 168–187 | VO₂ max, neuromuscular power |
What Each Zone Feels Like (Talk Test)
- Zone 1 · Recovery: You can sing.
- Zone 2 · Endurance: You can hold a full conversation.
- Zone 3 · Aerobic: Speaking becomes noticeably harder.
- Zone 4 · Threshold: Only short phrases of a few words.
- Zone 5 · Maximum: Almost impossible to speak.
