I have developed a webapp ride analysis using advanced ECP-ExRec models. ECP = Extended Critical Power, ExRec = Acute anaerobic Exhaustion and Recovery.
In this stand-alone app, the athlete browses for and uploads his data file in .fit format
I would like to integrate it into Strava as an authorized app. Is it possible to read the full content of a strava data file, such as timestamp, hr, power, alt, cad, etc...?
