Convert average rowing power to a 500-meter split or convert a known split back to watts using the Concept2 pace-power relationship.
How the Watts-to-Split Calculation Works
The performance-monitor relationship uses pace in seconds per meter. Divide the 500-meter split by 500, cube that pace, and divide 2.8 by the result to obtain watts. The reverse operation uses a cube root.
| Average split | Average power | 2,000 m at the same split |
|---|---|---|
| 2:05/500 m | 179.2 W | 8:20 |
| 2:00/500 m | 202.5 W | 8:00 |
| 1:45/500 m | 302.3 W | 7:00 |
| 1:40/500 m | 350.0 W | 6:40 |
Why pace changes nonlinearly
Power is inversely proportional to the cube of pace in seconds per meter. A small improvement in an already-fast split therefore requires a larger watt increase than the same number of seconds at a slower split.
Using the finish-time rows
The distance rows simply extend the entered split. They are useful for targets and interval planning, but they do not estimate fatigue or prove that the power can be held for the longer distance.
