EIRC Race Analysis


  1. Ric and I were looking at them earlier - my stroke rate is mental at the end!

  2. Mark - I thought that too! It's interesting how different our races are in terms of stroke rate and power ratios.
    I have been comparing my 2010 EIRC race to the 2012 one and my stroke rate and power output have totally changed (for the better). I know need to figure out how to go even faster without doing myself an injury. Some of the ladies I'm up against at the WIRC are pulling in times like 07:04... fast, very fast....

  3. These are fascinating. As a stats junkie I can never get enough data.

    Is this the sort of data you get if you have a C2Log card and reader?

    More importantly for me, though - I have no idea how you guys generate so much power per stroke. I find it impossible to keep the rate down if I pull at "full power", such as it is. And if the rate goes too high, I explode due to lack of lungs and through overheating.

  4. Hi David - these are the stats from the race machines, it's not quite the same as the data on the logcard. The erg records data 3 times per second and that allows C2 to plot these graphs, but the logcard just shows you the data as you chose to split it. I think rowpro might allow you to get more data out the backend, I don't use it though.

    Regarding rate, I always struggled myself, but the more I trained the better I got. It's important to keep the drag factor down - it's not about rowing on '10' all the time. I row mainly on a drag factor of 120-130, more 130 these days, and as part of my training plan I have to do rows in the various ratings, down as low as 18-20. I used to do everything at 30+, but doing the low rate work really builds up the strength, and I find I enjoy it (a little bit!) more.

  5. Thanks Mark. So far, using a lower drag factor has had me pulling more rapidly and feels unbalanced. I guess that's a technique thing.

    The animation on the concept website, and the description, led me to a technique that has a "finish" which leaves my body fairly vertical, limiting the stroke length. The images on this page: http://www.concept2.com/us/training/muscles_used.asp , however show a torso position that is more consistent with Caroline's technique from the videos she has kindly placed here (and also with some of the stills I've seen from the competitions.)

    I guess I'll have to work on that - it's going to take much more out of my upper body/core I think, which would be no bad thing.

  6. Hi David,
    I have worked really hard on totally changing my stroke rate over the last 3 years. In competitions it was as high as 40 stroke rates per minute and now as you can see on my graph I have got it down to under 30. I Aim putting much more power in with my legs and finish the stroke with a slightly angled back. Although its not a perfect technique ( I need to work on keeping my knees straighter - they are wobbling all over) I have improved my time year-on-year since slowing down my stroke rate.
