I suggest that users unpair on-water rowing data that imports into their scheduled workouts. The average human will never generate as many Watts on water as one can on the erg–hence the paradigm: “Ergs don’t float.”
Also, your HR will be much higher (probably from constant core engagement to balance the boat while sculling) on water than on the erg for any prescribed power zone. For example, one might be training aerobic development at SR18-22 on the water but have HR in the 150s for 80 minutes. Athletica appears to interpret this scenario as a lack of fitness and will drop your power zones to align with what Athletica believes should achieve a HR in the prescribed respective HR zone. When I was less fit and began this training 6 months ago, my max HR was 182 (age 51 (the oft quoted 220-age formula was incorrect)). Now I perform VO2max exercises on the erg and can’t get my HR above 172. Athletica says I should be able to achieve HR 180-191 at row power Zone 5 (2K pace). On the water, I can only routinely get my HR to 176 during high exertional training.
