No GPX data for get_moving_speed

[petermisovic]

Hello,
when I use following code to display average moving speed from GPX, I do not have any data shown in console:

new L.GPX(gpx_etapa_2_den_4, { async: false, polyline_options: { color: 'red', opacity: 1, weight: 5, lineCap: 'round' }}).on('loaded', function(e) { var gpx = e.target; Console.Log(gpx.get_moving_speed()); }).addTo(mymap);

Could you please help me with this code?

thank you
Peter
