Stuck by the side of the road when the meetup started

I was in a meetup a couple of days ago with friends. I joined a minute or so early, and was sitting on my virtual trainer by the side of the road with the other riders. When the meetup started, the other riders rode off, but I was stuck on my trainer for a couple of minutes. Never seen that before. Chasing them down wasn’t the recovery ride I was hoping for :slight_smile:
