Hi,
I’ve done a new comparison, this time of an old running activity. The activity on Sports-tracker shows a distance of 9.52km, and the GPS points of the route are almost perfect. I marked the same route with an online distance calculator (https://www.calcmaps.com/), and the result was 9.67km, practically exactly the 1.5% difference mentioned in the thread.
Here are the screenshots:

If, in your SportTracker activity, you open the “graphs” menu, you can show activity information over the map. If you move to the right (end of the activity) maybe you could see a final distance close to the 9,67km (the “Raw” measured distance).
Yes, that’s right, in that case the distance it shows is 9.65 km. It’s clear that Race 2 correctly captures the GPS points but then processes them incorrectly. In my opinion, this should be a priority bug fix.
I don’t know if it process de GPS data incorrectly, for sure it does it in a different way in comparison to other models.
