Right! Thanks for checking this.

The bug is corrected now on GPS-Sport.net and the unit is correctly set to m/s.

Now I am shore that if I download GPX file from for example http://www.gps-sport.net/trainings/running_1338412
Actions -> Download GPX
<SPEED> units are km/h
And if I export GPX from Run.GPS application <SPEED> units are m/s
I make a test on a car.

This is part of file export from Run.GPS

<SPEED>

Optional in: <wpt> <rtept> <trkpt>
Units: meters per second
<speed>4.23</speed>
Instantaneous speed at the point.

It is the same as the speed on the portal, which is computed using GPS data by Run.GPS (using a modified continuuos Douglas-Peucker algorithm).

Tell me please in what units I'v got speed when I download GPX file. Is it m/s or km/h?
And one more question how it calculated, direct from GPS or the same as speed on portal?

Best regards Denis
