Hi John,
Why do you use 2.75 when concept2 documentation says
Watts = 2.8/(pace*pace*pace) ?
In physics P = K * v^3 with K = drag*area*density/2
For water density = 1000kg/m^3
So concept2 basically says drag*area = 2*2.8/1000 on the C2.

Is there an adjustment factor for age too ?

For what it's worth, this formula is one of the metrics looked at in selection for the junior national team. I'm not aware of who started using it, but it has been around for a few years and provides a simple way of comparing athletes of varying (sometimes dramatically) sizes but similar scores. Perhaps where people are getting hung up is on the choice of vocabulary to describe it. Rather than "fitness metric" one could say a "weight adjusted metric".
That put sit into clearer perspective. A weight adjusted metric that is one (of several) metric(s) used to compare for team selection. Thanks AF for the clarification and history.

I found that forum on the internet. I apologize if I presented the wrong data without double checking.

Oh, no need to aplologize. I just wondered if you had some inside info that concept2 used rounded number in the documentation.
I enjoyed reading this thread. Weight adjusted performance is interesting

You all are so helpful and engaging, I feel a little guilty that my instinctive reaction was "How much do you earn?"

^ is the symbol for exponentiation (raising one quantity to the power of another).

Thanks chgoss and John!
John, we are quite close in weight, age and 2k time. Your low pull is a lot better than mine (1:26) though!
This is just a suggestion, but it would be interesting to know more about people's athletic background, their objectives on the erg, as well as what kind of training plan (if any) they are following.

I would love to hear any suggestions you have for me. My goal by the end of next year was to in fact, reach your 2k time (around 6:40) and "fitness". Let me know

I highly recommend the Wolverine Plan. It is a very structured and demanding plan but it yields results. It was designed by Mike Caviston (40-49 lwt WR holder and an expert in physiology, as well as a rowing coach).
In case you have not heard about it, here are some links about the plan:
This is the original plan:
http://www.concept2.com/forums/wolverine_plan.htm
And here is a discussion thread on the old forum about the plan:
http://www.c2forum.com/viewtopic.php?t=4190
There is also a current thread on the UK forum:http:/
www.concept2.co.uk/forum/viewtopic.php?t=14425
IMHO, if you are relatively new to erging and have not followed any structured erging plan before, then you are very talented and improving from 6:57 to 6:40 can be achieved within 6 to 8 months following such a plan.

I am actually a first year rower (novice), however our season just ended a few weeks ago. Whats funny is that our varsity's team calls themselves wolverines, lmao.
I've always been good at stamina as well. I'll check out this plan later tonight and let you know what I think, thanks Francois!
