Mud Pack (also known as Mud Run) is a recurring Reward Challenge of Survivor. Debuting in Survivor: Borneo, it has since been reused in Survivor: Cook Islands and Survivor: Cagayan.


Under a time limit, tribe members dive into a mud pit and cover their body with as much mud as they can. They then race back and scrape it off into a bucket. They cannot carry mud in their arms or in their hands, only their body. The buckets are then weighed, and the castaway with the heaviest bucket wins.


In Survivor: Borneo, the contestants returned to the mud pit of old Pagong camp to compete for cold beer and a trip to a bar to watch the first five minutes of the season. The castaways had five minutes. The winner was Kelly Wiglesworth.

In Survivor: Cook Islands, the castaways had to dive into a pool of mud and cross an obstacle in the way of return. The three castaways with the heaviest buckets after ten minutes would win a night at a spa. Ozzy Lusth, Parvati Shallow, and Yul Kwon won.

It appeared as the final five Reward Challenge in Survivor: Cagayan. After ten minutes, Tony Vlachos' bucket was literally overflowing with mud. Because of this, the other castaways elected not to have the buckets weighed and Tony was deemed the winner.
