It would take approximately 4 days and 18 hours to watch all episodes of The Flash without breaks.

Estimated Duration: 4 days

As of 2023, The Flash has around 9 seasons with approximately 170 episodes, each averaging 42 minutes. To watch all episodes back-to-back without breaks, it would take roughly 4 days and 18 hours (or 119 hours total). For a more manageable schedule, watching 2 episodes per day would take about 3 months to complete. Binge-watching 5 episodes daily would take around 5 weeks. The exact duration depends on your viewing pace and whether you skip intros/credits.
