The main The Traitors final episode usually runs a little longer than a standard instalment, at around 70–75 minutes depending on the specific series and version.

Typical UK BBC finale length

For the UK BBC version of The Traitors , recent seasons have had extended finales rather than the standard 60‑minute slot.

  • One recent BBC season finale was scheduled as a 75‑minute episode instead of the usual hour.
  • Another season’s UK final was listed with a 70‑minute running time, again a bit longer than the regular episodes.

US Peacock version runtimes

The American version on Peacock follows a similar pattern of making the last episode longer and pairing it with a reunion.

  • A previous US season’s finale lasted about 1 hour 13 minutes.
  • That finale was followed by a reunion special of about 1 hour 6 minutes, so if you watch both back‑to‑back, you’re looking at roughly two‑plus hours total.

Why the final is longer

The final tends to run long because it has to cover missions, the last banishment(s), and the full reveal of who is Faithful and who is a Traitor.

  • There is usually extra time for the end‑game voting and the reveal of the winners at the “Fire of Truth”–style end sequence.
  • Broadcasters often slot in a companion or debrief show right after the finale, which extends the viewing time for fans who stay tuned.

TL;DR: Expect the core The Traitors final to be around 70–75 minutes, and closer to two hours of viewing if you include any reunion or recap specials.
