All rides go the same way at split road during Team Time Trials
I get the fun of the split road in normal races, but a team would generally go the same way in a time trial. If we have riders that can't easily get to controls, we are effectively punished if a rider by chance goes a different way. All riders should follow the same route, as happens if riding with a pacer.
Many thanks for your suggestion and support for TrainingPeaks Virtual.
I'm delighted to say that this is already fully implemented. As you note, when following a pacer then everyone will go the same way across a split road, but the same is also true for Team Time Trial events.
If you saw different behaviour then that will be either because it wasn't a Team Time Trial event (maybe instead it was set up as just an ordinary scratch race, rather than using the specific Team Time Trial mode), or because one of the riders chose (either deliberately, or accidentally) to go a different way from the default (where the default would have been the same for every member of the team).
