Rowing and Cycling Watts

Post by Meek » August 30th, 2019, 8:07 pm

If you row, and regularly or occasionally cycle, how do your watts compare? Similar for distances up to 20min or so? 5min power? Thanks.

5K on the erg....>30W lower c/w the bike (but I'm comparing 2017 ergo to 2015 bike and in 2015 I was more cardio fit than I've ever been since). Do a search on the forum as topic has come up before. The "problem" is power delivery is continuous on a bike whereas on the recovery with the ergo you're producing no power so will always tend to be lower.

Very difficult to get a direct comparison, the motion is totally different.

The problem has already been covered by those wanting to use the Zwift cycling software using a Concept 2 rower instead of a bike.

It looks to me that the Watts at about 200W, which is about 30km/hr on a road bike on a flat road and 200W on the Erg which is 2:00 pace line up in terms of "intensity" or a matching heartrate but outside that it goes to the weeds. You body weight, ability to change gears on the bike, hills on the bike throw it all out.

Some sort of pretty complex formula that was derived from taking the same person on the bike and then on the erg and basing the conversion on heartrate would need to be derived. I cannot think of anything else but using your heartrate as a major part in deriving the formula that at least puts you somewhere where you should be in a peloton had you been on your bike instead of the rower or its going to be no "Fun" let alone something that can be used to compare your performance on a rower to that of a bike.

I use both the Concept 2 BikeErg and the Rower on a regular basis. I'm close to my best on the BikeErg, but my best rowing days were a few years ago. I'm quite well balanced between sprinting and endurance.

Peak power on the BikeErg is around 1:07 / 1150w. Peak rowing power is lower at around 1:13 / 900w.

Peak 1 minute is very similar. 1:20.4 on the bike and 1:20.0 on the rower (683w v 674w)

Best 4km BikeErg is 6:04.9 (461w) versus best 2km row of 6:15.9 (421w)

As the distances get longer and longer the gap increases more and more. Cycling is way more efficient over longer distance than rowing.

30 minute row = 1:42.3 (326w) versus 1:37.9 (373w) on the BikeErg.

I've done 293w for a 100km BikeErg which took 2hr 56.x mins. If I'd rowed for that long at my peak I'm guessing I would've been around the 1:54 mark (235w) so quite a lot less.
