Heart Rate vs. RPE Conversion Chart
Check out this chart to compare heart rate and RPE.
| Type | Zone | Power (% FTP*) | H/R (% FTHR*) | RPE (3-20) | Effort Level |
|---|---|---|---|---|---|
| Recovery | 1 | <55% | <72% | <6 | VERY EASY - You should be working and sweating but not a big effort. It should be very easy to carry on an uninterrupted conversation. |
| Easy Endurance | 2 | 56-75% | 77-83% | 7-11 | CONVERSATIONAL - An effort you can sustain for an extended period of time without fatigue. Slightly interrupted conversation. |
| Medium Endurance | 3 | 76-90% | 82-94% | 12-14 | STRONG, NOT BREATHLESS - Effort is strong but sustainable for an extended period of time. Comparable to half-marathon or IRONMAN® 70.3 pace. |
| Threshold | 4 | 91-105% | 95-105% | 15-17 | HARD - This is your maximum steady, sustainable effort. You should be able to hold this for several minutes. Not a comfortable pace. |
| Power | 5 | 106-130% | >106% | 18+ | VERY HARD - This is an effort or speed you can hold for only several seconds to a very few minutes. This zone includes all high-end speed work. |
