I did my first field testing yesterday and just looking for some input to make sure I'm doing things correctly in Golden Cheetah Aeorlab. I have my testing parameters below as well as some screen shots. I've read through as many threads here as possible but now looking for some personalized feedback. If anybody has time for some feedback it would be greatly appreciated!
Course - 3 loops for a total of ~2.04km. Each loop has some sharp turns that causes a bit of coasting but no braking. Did my best to hold the same line on each loop. Has incline and decline that allows for variable power. No wind.
Bike - Speed Concept, Garmin 500 (GPS off), PowerTap P1 pedals, DuoTrap for speed.
Goal was to test my usual 2XU sleeve-less jersey to a new Castelli Stealth sleeved jersey. Also, tested road (Giro Atmos) versus aerohelmet (Giro Advantage 2).
Results (assuming I did things correctly in Aeorlab)
I did 3 tests with each setup and then ran them a second time.
2XU w/aerohelmet - test one 0.258, test two 0.2602
Steath w/road helmet - test one 0.2669, test two 0.2695
Stealth w/aero helmet - test one 0.2683, test two 0.2628
Curious if the repeats for each test should be closer in value?
I have screen shots of Aerolab below. What I'm doing to get the CdA is measuring the elevation at the beginning of the blue line by hovering over it and then sliding the CdA until the end of the blue line matches the beginning elevation. Once they match I assume the value on the CdA slider is my value. Is this correct?
I have screen shots below. The first is of the complete test (I was hitting Lap at the beginning of each test). I then broke it into separate rides in GC. The second shot is data before adjusting CdA. Third shot is after adjusting CdA slider to get the beginning and ending elevation to match. I then did that for each run.
If this is all accurate then I'm kind of disappointed that the Stealth would be slower than the sleeve-less. Also the aerohelmet doesn't appear that much better than my road helmet. Or perhaps my data is all crap and I wasted and hour!
