Rules
In this challenge the tribes would one at a time go across a obstacle course.

Once across the balance beam you go through a tripping net, and then you swim to the finish, the first tribe with everyone at the finish wins Immunity!

History
In Survivor Marquesas, Maraamu got off to a slight lead ahead of Rotu, then it went downhill for Maraamu. Rotu took a very large lead and were doing really well on all of the obstacles. Then, Hunter got stuck on a segment for a little while, getting Maraamu lapped by Rotu. Hunter did end up completing his round, but a that point Maraamu was to far back and they couldn't catch up.
