How it works

Any two of time, distance and pace fix the third. The dot on the monitor shows which two you set; the third is calculated. Change watts and the pace follows.

Watts use Concept2's formula: watts = 2.80 / (pace ÷ 500)³, with pace in seconds per 500m (per 1000m on the BikeErg). Calories per hour are watts × 3.44 + 300. BikeErg pace is shown per 1000m, so a 2:00/1000m on the bike equals a 2:00/500m on the rower in watts.
