Hi
In the webpage, fitness and freshness is retrieved from here
https://www.strava.com/fitness/{athlete_id}?range=3months&type=&source=combined
What is the equivalent endpoint in the API to retrieve that information?
Thanks
API endpoint to retrieve fitness
+1
+26You have to calculate everything in your app by using the suffer_score in the activities and the power values, the Strava API doesn’t provide an endpoint,

Thanks! Is there any guide on how those figures are calculated?
+26Not really, you have to do much research and then you will only get near the undisclosed Strava formulas. Basically the Relative Effort is calculated by totaling all suffer_score from the same day and then you have to use the formula “Relative Effort for today” = “Relative Effort from day before” + “Total suffer_score” / 42
The same formula can be used for the power instead of the Relative Effort, but as the Strava API doesn’t reveal the training load of the activity you have to calculate that by the formula “training load” = (weighted_average_watts/FTP)² * moving_time / 36
