Snake Island Relay

Waiting to Exhale is a recurring endurace physical challenge of Survivor. It debuted as part of the first ever individual immunity challenge in Survivor: Borneo and used again in Survivor: All-Stars.

Rules
The challenge requires survivors to hold their breath for as long as they can.

History
In, all ten castaways submerged themselves underwater to see how long they could hold their breath. The top three castaways then had another competition of releasing buoys along a ladder submerged underwater. The first castaway to release all of their ten buoys would win immunity. Greg, Gervase, and Sean made it to the final. In the final, Greg barely beat out Sean for Immunity.

In, the castaways were divided by sex. The two people of each sex to stay submerged longer pass to the second stage. In the end, the two finalists from each gender have to race to unclip buoys. The two winners would win immunity. Amber and Kathy was the final women, while Lex and Rob was the final men. The women went first, which Kathy defeated Amber for immunity. Rob then defeat Lex for the men's individual immunity.
