Exactly four months ago, we were debating the effects of watts output going up a hill vs. down a hill.
I asked for some distance vs. altitude data in order to try to optimize power vs. time. Dr. W. responded, but unfortunately, the info/data he gave was from one of the various topo programs; this data was much too rough/incorrect to be useful.
So a few months go by, and I realize I should probably try to get some Garmin data and attempt the same thing. Asmallsol gave me some for a prologue TT we both competed in this past May. Fortunately it had some simple hills in it that would be useful for testing the optimization algorithm.
The algorithm uses Normalized power. My Normalized power isn't exactly the same as Allen and Coggan's, because it's difficult to take a thirty second average when you're in the distance domain; but it uses the same basic concept. The computer, of course, doesn't see a downside to you putting out 100 watts one second and 700 watts the next, so after I got my results back, I applied a simple digital smoothing function to them.
The results are below.
Only three more months of crappy cycling weather.
