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.

Do you mean on a road bike, or bikerg?

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.

Hi,

This is a very interesting question, and something that I have been puzzling about also.

A more general comparison and outside the Concept 2 ecosystem: road bike vs erg

This past summer I put a power meter on my road bike and focused on improving my cycling. The erg results are more recent and were performed without any foundation/base work on my Concept 2, but are the beneficiaries of the residual fitness gained out on the road over summer. I have not done any short pieces on the erg thus far to add a comparison, but here are my 2019 results to date:

Cycling Results:
1. 30min: 267W (Aug-19)
2. 1 hour: 243W (Aug-19)
3. 20min FTP test (generally regarded as the cycling litmus test): 296W (Sep-19)

Concept 2 Results:
1. 30min: 192W (Sep-19)
2. 1 hour: 184W (Oct-19)

To be honest, I didn't realize that there would be such a discrepancy between the two data sets. I have to say one of the things that I have learnt/observed about cycling with power is that it is relentless. I never realised how much time I had spent off the pedals during a decent etc. I am able to maintain a very consistent pace on the erg for my long pieces, but (of course) out on the road, even when consciously making an effort, power fluctuates massively.

Not sure whether the 1hr test was all-out but that ought to be alot closer to your 20mins power. Furthermore FTP is generally used to denote 1hr max power not 20mins max. I strongly suspect as you erg more the numbers will get quite alot closer to your bike power. Thanks for sharing...

Very astute!
You are 100% correct on the 1 hour cycling numbers. The training program records the best power for period that I have had this season. The FTP test was the only all out effort that I did. The 30min and 1 hrs were "best result" periods as part of general training rides.
Cheers - I am looking forward to the challenge of improving the erg numbers!

For what it is worth 62 ,6ft 1 ,94 k

10000 mt fixed distance on on concept 2 rower 3 times per week av 204 - 206 watts for time between ,generally , between 39.40. -39.55
47 mins fixed time on Keiser m3i bike 2 times per week generally averages 205 - 210 watts

Stuffed at end of both .Only conclusion I can make is that 47 min on Keiser bike is roughly equal to 40 min on concept 2 rower
