Running and Rowing: Exploring the 10K Correlation
Conclusions


Back in the Fall '99 issue of the Update, we invited runners who row (and rowers who run) to let us know how their 10k times compared between the two sports. Since then, we have heard from quite a few people about their cross-training experiences with running and rowing. We're not sure we can offer a definitive theory on the correlation between the two, but we're quite sure you'll enjoy hearing some of the stories.

They're Different!

I ran for about 20 years, until my knees started bothering me and I switched to rowing. I ran several 10ks in my thirties. The best time I was ever able to achieve (after running over 100 miles in more than a month of preparation) was 45:20. Now I am over fifty and use my rowing machine about 4 times a week. Without much hard work, I am able to row a 10k in 38:30. I have a feeling I could do much better if I ever seriously trained for a 10k row. That is a 15% better time on the rowing machine, which I believe is significant.

I am 36 years old, and have been rowing on my ergometer (Model B) regularly for approximately 9 years, which includes through 2 pregnancies. I started running approximately 2 years ago. Perhaps it is because I have been rowing so much longer, but I am considerably faster on the ergometer than I am on the street. My fastest 5000meter row, done February 28, 1999 is 20:56.2. My fastest 5000meter run, done in a local 5K race on May 23, 1999 is 23:29. My best time for a 10K row is 43:21(May 1999), and for a 10K run is 49:53 (May 1999).
I enjoy these workouts a lot, and hope to continue both, but I strongly doubt that my running times will ever approach my rowing times.

I am a runner, mostly of marathons (2-3 annually), but also run 10Ks as part of my training. My PB is 43:6. I bought a C2 rower about 3 years ago for cross-training. Nowadays, I generally do rowing distances in the 5-6K range, but I used to do 10Ks when I first bought the machine. Even then, I was only rowing about twice a week, but my PB for 10K was 40:08 at a damper setting of 7. In other words, I am a runner whose best running time is worse than his worst rowing time. I suspect this means I'm in the wrong sport, at least from a performance standpoint. Broad shoulders and ample upper-body strength aren't a lot of help in running. On the other hand, I'm an outdoor kind of guy, and that's where the running is. Only the Canadian climate keeps me indoors.

They're the Same!

It's like you read my mind: I'm one of those runners who uses the rower for cross-training, and I've noticed for years the striking similarity of my running and rowing 10K times. 10K run; 38:50, row: 37:28.
I often sound like a salesman for Concept2, extolling the virtues of your rowing machine. The facets that I find particularly amazing are: 1) I can work harder on it than on any machine or running (except for a race); 2) it seems to work the opposite set of muscles vs. running, and generally works many more of them; 3) I can row injured or sick, and it seems to help dramatically; particularly with injuries caused by running, it seems to smooth them out.

I recently read your newsletter and found it interesting that you're comparing running times with erg times. I happen to be both an avid rower and runner. My best 10k erg is 37:40 and 10k run 37:50. For some reason I never made the obvious correlation between the times.
J.M.

With thirty-five years of competitive running and "only" ten years of rowing for complementary fitness, I find that the times, as you suggest, are very close. I actually use the rower as a better or honest monitor for dehydration, overtraining and threshold capabilities. My advice to cross-trainers who are expecting a close match is to compare training times only...there is an awful tendency to compare the race times of your specialty and then expect the same for the complement. Big mistake.

Conclusions?

Well, as you can see, for some people the correlation is remarkable, and for others non-existent. What's up? Our review of the data we received suggests that there are a couple of factors which may determine whether or not you will see a run/row performance correlation.

  • Your size (height and weight): Larger size (even if it's all muscle!) can slow your running times because you have to carry all your weight with you. The seated nature of rowing means that you pay less of a penalty for larger size. We believe that in general, larger people will have faster rowing times.
  • Experience: It may take a few years for rowers to achieve their personal bests at running and vice versa. Give it time.
If you're headed back out to the roads and trails this summer, but still rowing occasionally, let us know if you come up with any other theories to explain our findings. We'd welcome your insights.
