By default, Tracks4Bikers’s Builder uses Google Directions in order to set labels to trackpoints.

For example, a direction text like “Turn right at street London” is translated in a “street London” point label (with also a right icon)

This is good if you use the track in a GPS device, but the resulting profile results a little poor

An alternative is retrieving geonames entries from http://geonames.org website. You can enable this feature by selecting “Geonames (slow)” option in the combobox near “Labels”.

This option requires some queries to the geonames webservices and so it’s a little slow; you must wait a little until it completes.

This is the same profile filled with geonames:

And, finally, you can display both direction labels and geonames, by selecting the option “Both”

Obviously, the best solution is to manually edit the point labels!
