finally a solid data set with not a whole lot of wind and a 40k flattish TT.
Since my power has dropped off the map I forced myself to be as faithful to the position as possible, although I stood up every 10-15 minutes, plus the turnaround.
Aerolab came up with a CdA of .203 which does seem quite possible. Theoretically, once I regain strength, the speed improvements will be pretty astonishing, although it may be that the position robs me of some of that strength.
Last season, when I was still in relatively decent form, I was able to make .96 of measured FTP in this position.
So far this year, either my FTP has descended into the basement, or I am only able to make .90 of measured FTP. I've been able to do a few shorter interval sets @FTP in this position, but for the long TT, it worked out to .90
One thing I have discovered is that a regular hamstring and calf stretching program helps, as it is what I am NOT doing this year.
Still, the speed is a wash, so any improvements in power should eventually mean PRs in time trials. Just for fun, I calculated what I could "theoretically" do at last year's peak FTP and .2 CdA. That came out to more than 28mph. Here's hoping...
