Ski Training - Interval Experiment

Tried the interval training suggested below on surfski.info, but with 10kn on the beam & crappy short wind chop it wasn't that easy in the V12. Interesting that the Ergo workout at a much higher cadence, with a nominal faster speed speed produces an average heart rate way below the same sort of workout on the ski, where you're working hard on additional things like balance.

You can see the three 2 minute interval bursts on the graph, and also how much more effort you expend paddling down or across a sea, must be the higher cadence, maybe a bit a adrenaline too. The 40 minute mark is where I turned & ran back on a quartering sea.

Interesting…!
