add speed to .gpx

[Lobotron]

but with no speed data - I can not find anything for calculating and adding speed to .gpx :-/

Dear Marek,

if the .gpx contains time stamps then you can let RouteConverter calculate the speed by Positions->Complete->Speed

Hi,

I konw it - problem was in .gpx - my .gpx saved from video has many points with the same time. When I removed them, everything started to work
