Reverse Engineering Power Data

Hi, since i don’t have power meter, i am curious about how correctly Strava estimates power on road routes. any idea?
or any other tool that calculate power based on speed/grade from “gpx” file?
thanks

  • First, I think “correctly” is a very dangerous and likely bad word to use with Strava power estimates.

  • Seconds, as usual, google knows:
