Yesterday, on a course of 10km I tried to use the function: TRAINING>YOURSELF (race against yourself), three days before I had run the same route, so I tried ...
I was happy during the ride, because after 1km the clock told me to be already ahead by about 200 meters from the trainer, despite not much was forcing.
At the end of the ninth kilometer, the clock alerts me that the trainer takes the lead.
At the end of the session, the trainer has won, and at the time of his arrival, the clock told me he has arrived with a lead of 163 meters.
When I downloaded the workout on the PC and compared the two paths on Sporttracks3, I discovered that overtaking by the trainer has occurred much earlier (at the third kilometer), where instead the clock was telling me to be ahead of about 200 meters.
Someone has already tried this feature?
If it can be useful, the two training files are available here
I apologize for my crappy english.
