Race-simulation workouts

Thought about this in my workout this morning, I can’t be the first to think it up:

When will we get race-simulation workouts, with “hidden” intervals? For example, you know you committed to a 45-minute crit workout but do not see the intervals in advance, as in a race. Unpredictable attacks, recovery, solo breakaways, covering, finishing sprints, all could be integrated.

What say you, TR?

There are plenty of race sim workouts (Blue, Blood, Barren, Tour de Nez). And you could easily just cover a portion of the screen with a post it.
