How Does My Power-to-Weight Compare to Others?
An isolated number is meaningless when you can’t compare it to others. The following charts are simplified versions of those in Training and Racing with a Power Meter, 2nd Ed. by Hunter Allen and Andrew Coggan, Ph.D. They show the different men’s and women’s levels.
Remember that the following figures are estimates that are constantly evolving and should be taken with a grain of salt.
| Rider Level (MEN) | 5s | 1 min | 5 min | 60 min (FTP) |
|---|---|---|---|---|
| World Class (International pro) | 22.8< | 10.6< | 6.8< | 5.6< |
| Exceptional (Domestic pro) | 21~23.4 | 9.9~10.8 | 6.2~7 | 5.2~5.9 |
| Excellent (Cat 1) | 19.3~21.6 | 9.2~10.1 | 5.5~6.4 | 4.6~5.3 |
| Very Good (Cat 2) | 17.5~19.9 | 8.5~9.4 | 4.9~5.7 | 4.1~4.8 |
| Good (Cat 3) | 15.4~17.8 | 7.7~8.6 | 4.2~5 | 3.5~4.2 |
| Moderate (Cat 4) | 13.6~16 | 7~7.9 | 3.6~4.4 | 3~3.6 |
| Fair (Cat 5) | 11.9~14.2 | 6.3~7.3 | 3~3.8 | 2.4~3.1 |
| Untrained (Nonracer) | <12.4 | <6.6 | <3.2 | <2.6 |
Here are the power numbers for women.
| Rider Level (WOMEN) | 5s | 1 min | 5 min | 60 min (FTP) |
|---|---|---|---|---|
| World Class (International pro) | 17.7< | 8.6< | 6< | 5< |
| Exceptional (Domestic pro) | 16.4~18.3 | 8~8.8 | 5.4~6.2 | 4.5~5.2 |
| Excellent (Cat 1) | 15.1~17.8 | 7.5~8.2 | 4.8~5.6 | 4.1~4.7 |
| Very Good (Cat 2) | 13.8~15.5 | 7~7.7 | 4.3~5 | 3.6~4.2 |
| Good (Cat 3) | 12.3~14 | 6.3~7 | 3.6~4.4 | 3~3.7 |
| Moderate (Cat 4) | 11~12.7 | 5.8~6.6 | 3~3.8 | 2.5~3.1 |
| Fair (Cat 5) | 9.7~11.5 | 5.2~6 | 2.5~3.2 | 2~2.7 |
| Untrained (Nonracer) | <10.2 | <5.4 | <2.6 | <2.2 |

How Do I Determine My Power?
Determining your cycling power involves using a power meter or a smart trainer, which measures the amount of force you apply to the pedals and calculates your power output in watts.
The Power-to-Weight ratio is usually calculated based on a certain period for better explanatory value, for example:
- 5s power | 5s w/kg
- 15s power | 15s w/kg
- 1min power | 1min w/kg
- 5min power | 5min w/kg
- 20min power | 20min w/kg
