I usually divide warm map training (10min of slow pace run) to the real training (this is what my coach wants).
I use GCW or GC app to schedule them in a day and then sync the watch.
Really often (80% of the times) the warm up training is missing when I go out and starting my run.
I start "Run" and the watch offers me the list of the training on that day and often the warm up one is not there. I saved it on the watch so I can easily find it, but I don't understand why it isn't send from GC to watch correctly,
This happens since 2 or 3 offcial releases
