Hi Peter - We don't import speed data into plotaroute at present. We've taken the decision to focus on plotting and sharing of routes for now, as adding speed information would open up the whole area of fitness tracking, which could make the site much more complicated to use.

Can Plotaroute show the Speed info from an uploaded track from a Garmin GPS device, if I upload to Garmin Connect I can see Speed info (max, avg etc) and elevation info , but I cant see how to view that in Plataroute?
