"b3yy copy the last 3 lines into buffer bĬhange the name of the track to add " section 1" "a8yy copy 8 lines into buffer a (or however many lines it is above the first ) This is based on a track gpx from avel, that has 1 line per, 8 lines above the first, and 3 lines after the last If it's a one-off split into 5 files, use vi. Once you're familiar with the program it would take less than a minute to do. You can right click on these individual parts and save them independently. In the left hand 'Track Pane' expand the track by clicking on the '+' symbol and you will see that the original track is now made up of several parts. You can do this as many times as you like. The test file I used had approx 1800 pts and all I did was scroll down to point 6 in turn, right click, select restructuring and add break. Make sure View - Panes - Points and tracks are both selected and on the RHS of the page will be the 'Points Pane' where you can see an easy to read numbered table of every point on the track. (This will mean that you'll now be working with a'Track' with timestamps - not sure whether this will be an issue for you) Selecting File - Open Track (when in fact all you've got is a route) will cause the program to ask what you want the first timestamp to be and what speed you'd like to have programmed in to the track.
I use it for cleaning up GPX tracks quite a bit.
