Hey @Jozhua, 

Thanks for your post! It's common to see small discrepancies between your device distance and what you see on your Strava activity page. These are due to number crunching on both ends - Strava processes and analyzes the data in the file independently.

For more details on this process please refer to this article. 

Hi,

I had same issue as yours. The differences quite a lot. In strava, detect 2 times of the actual distance. 

Yesteday I only running around 5K, but in strava detect it as 10K. When I check the route and play the visualization in strava, i notice after I finished my activities, strava will tracking my activity from the start again until finish. That's why the total distance is 2 rimes from the actual distance.

I'm using samsung A52S 5G smartphone as my gps.

I'm still looking for an answer for this too.
