Rowing split & pace.
Turn a 500 m split into a projected finish time, speed, and a rough indoor-rower power estimate.

Split formula
Total time = 500 m split × distance ÷ 500. Average speed is 1,800 ÷ split seconds in km/h. The watts estimate follows the commonly used Concept2-style relationship 2.80 ÷ (split/500)³.
The projection assumes an even split. The watts number is an ergometer estimate, not a reliable prediction of on-water speed or another athlete's power.
