Virtual Elevation Revisited

Just as a follow up to last winters post The World is my Aerolab, I thought I would link to a little video that sums it up nicely.  Much more digestible than reading Robert Chung’s full paper (although I encourage that).  (edited to add:  the part about VE starts at about the 28 minute mark.)

I have spent a fair amount of time helping others get started in doing this.  It’s a pay-it-forward type of thing for me.

You do need a power meter to do true-blue Virtual Elevation type testing.  And that’s a very versatile and precise method.  But, there are coastdown methods you can do to determine CdA and Crr for those who don’t have a power meter, but have some sort of recording type bike computer, such as a Garmin 500.  You do need an auxiliary speed sensor, though.  Not a big deal.

This BROL post (written by me) gives some step by step details:

Just email me with questions, folks.
