This question is a follow-up to:
The answer to that question is yes. Acting according to the following sequence should then enable a rogue (of at least second level) to triple their maximum movement in one round, right?
- Bonus Action: Cunning Action -> Dash
- Movement: move twice your speed
- Action: ready additional movement
- Reaction: move your speed
To clarify: The idea was not to move as far as possible on your own turn (which can be more easily achieved by simply taking Dash as a Bonus Action and as an Action, as was pointed out to me in the answers), but to spread your movement over several turns by using the reaction.
