AFAIK, TR only adds “Openers” to the schedule, assuming you select that option during the Plan Builder. An Opener is meant for the day before the event, and are different from a warm up meant for shortly
TR PB does not have an option for adding pre-race warmups (the focus of this specific topic). Those must be added manually by each users if they want them.
If there is confusion about which precise workouts TR adds for “Openers”, that is likely best addressed via support@trainerroad.com. My info in this thread and that other one are derived from TR podcast episodes and related searches for these efforts in the Workouts section. My info may be out of date if they have changed their approach.
