Prepare
Choose UT2, UT1 or AT, then set the duration and stroke rate. The optimiser evaluates a constant pace and useful equal-duration pace blocks against your complete heart-rate band.
Execute
Take the pace boundaries and five-minute HR reference to your PM5. Pace is a starting instruction; heart rate remains the physiological guardrail when the forecast and the day disagree.
Learn
Record with ErgData, which synchronises the result to your Concept2 Logbook, then choose the completed row here. Qualifying FIT data teaches the model how quickly your heart rate settles, how it responds to power and how cardiac drift develops over time.
THE INPUTS
What the model actually uses
- Your rowing heart-rate profileResting HR, maximum rowing HR and the source of that maximum.
- Comparable Concept2 sessionsPower, pace, stroke rate, heart rate, duration and five-minute behaviour.
- Execution qualityOnly sufficiently clean sessions should materially influence later forecasts.
- Forecast uncertaintyLimited or dissimilar evidence is shown as lower confidence rather than disguised as certainty.
TRAINING PACE VS TEST PACE
A prepared pace is not a race prediction.
This matters most at AT. Rowing Zones forecasts the pace most likely to keep your heart-rate response inside the AT band for the complete continuous session. It is not predicting your fastest 20-minute or 5,000 m performance; a test may be faster and take heart rate above AT.

IMPORTANT DISTINCTION
It is not a generic training plan.
Rowing Zones does not decide how often you should train or replace a coach. It solves a narrower problem: when you have chosen a continuous UT2, UT1 or AT session, what pace structure is most likely to keep the work inside the intended zone?
