Mean Maximal Power Curve


The above chart graphs two sets of data. On the bottom: duration. On the left: Maximal Power. This represents the best level of sustained power, ever, for the corresponding duration. The reason there are two graphs is because one of them represents my 2007 season (in dashed lines) and the other represents 2008 year to date. The very best data comes from racing of course, and since racing thus far has been limited, there is a large disparity, especially in the durations under 5 minutes. In Peaks software, if I drag the cursor over the graph, it gives the peak watts for that duration, along with the date when it was achieved. I've given an example up there. Pretty slick if you ask me..

I suggest you run the graphs for the same time period for each season, i.e . one line for 2007 Q1 and another for 2008 Q1. That's more meaningful than plotting the 08 preseason against last year's peak. But you don't have *any* data for 2007 Q1, because you didn't touch your bike until May last year, right?

You are correct, partially. I only have power meter data beginning from May 12 of 2007. Prior to that I have only Polar HRM data.
I started riding February of 2007, so there's data, but it's useless.

Well for this year you can see that all your specific test durations stand out clearly. You need some TT data. In races, the effort goes all over the place (unless you're off the front alone) so I would not expect any meaningful data for longer durations.

Data is fun to play with, but be cautious about making conclusions. I had some very interesting conversations with knowledgeable people (with decades of experience, both riding and coaching) this week, guys who weren't afraid to admit that there are some things about training they just don't understand. They just know what works.
