How the Rowing Split and Watts Calculator (Concept2) works
Concept2 rowing machines convert pace to power with watts = 2.80 ÷ pace³, where pace is seconds per metre. Because power rises with the cube of speed, shaving a few seconds off your split takes much more power.
Times for longer pieces assume you hold the same split.
The formula
Worked example
Using the default values shown in the calculator:
| Split minutes | 2 |
|---|---|
| Split seconds | 0 |
| Body weight | 80 |
- A 2:00 split is 0.24 s per metre.
- Watts = 2.80 ÷ 0.24³ = 203 W. A 2K at this split takes 8.00 minutes.
Result:
| Average power | 203 |
|---|---|
| Watts per kg | 2.53 |
| 2K time (minutes) | 8.00 |
| 5K time (minutes) | 20.0 |
| 10K time (minutes) | 40.0 |
Frequently asked questions
What is a good 2K time?
It depends heavily on age, sex and weight. Many fit adult men row 2K between 6:30 and 7:30 and women between 7:30 and 8:30; elite rowers are under 6 minutes (men) and about 6:30 (women).
