I started my watch too late on a 10k run. I had already run 1,5k when I started my watch. So my tcx-file only contains the last 8,5k. I did mark every 1k timelapses so I just have to add time equal to 1,5k at the front so the distance and time will match the marked 1k timestamps. As I see it I can add markers but only 'inside' the already recorded tour. Can MyTourbook add extra time to my tour?
no, not yet, time is always computed from the recorded data but manually you can create a new tour and set values which where not recorded so that your statistics are correct
