calibrate near sea level, use PP at altitude?

Post by flahutewannabe »

Question of curiosity. I did my calibration at approx 800ft elevation, now am vacationing in CO riding at 6,000 feet and will do some climbs around 11,000 ft. Anything i need to tweak, or will my reported power be good to go? BTW, I already know I'm sucking wind as a flatlander and can't put out my prev power numbers while my HR is skyrocketing... :shock: :roll:

This is a nice question!

A subtle but important aspect of PowerPod is that the "wind" sensor does not measure wind speed; it measures air pressure.

Therefore, when you change elevation, from a place where air is dense, to where it is less dense, the PowerPod remains calibrated.

Pretty amazing technology, John. Thanks for all the good work here.

Downside is that PPod is both accurate and precise, which takes some of my potential excuses off the table. :roll:

Nah...there are lots of arm chair physicists out there. They make excuses, even when they are untrue! :-)
