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

Thank you.
But it's a little bit strange for me because of my last activity.
If you can look at GPX file of my track 10.03.2014 12:05:00 PM, 5.56 km, you will see that for a long time I run faster then 10 meters per second
I am really proud of it, but can't believe such a good result :)
And all so when I try "training simulator" it show me speed in about 10km/h and it's seems to be ok, because it was orienteering.

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?
