What Is the Longest ‘Survivor’ Challenge to Date? Details

The longest Survivor challenge to date lasted nearly 12 hours! In Season 10, Survivor: Palau (the OG Last Gasp season), the top three contestants — Katie, Ian, and Tom — competed in a grueling final immunity challenge titled Bob-Bob Buoy. The task was simple: grab onto a buoy and hang on for dear life. However, the castaways’ million-dollar tenacity truly upped the ante. With the final two within reach, Katie, Ian, and Tom would stop at nothing to ensure a one-way ticket to Survivor victory.
