Splash Back

I Hold On (also known as Splash Back) is recurring individual endurance challenge that originated in, and was modified for re-use in and. It later returned to its original concept in.

Rules
Each contestant holds onto a rope whilst leaning out over a pool of water and balancing on a small platform. At designated intervals, the contestants will be lowered, increasing the angle at which they hang over the water (either by moving their hands down the rope, or by a crank automatically lowering them). Last person holding on wins the challenge.

History
The challenge debuted in as an individual immunity challenge. The contestants held onto a knotted rope, moving down to the next knot at five minute intervals. Jane Bright held on the longest, winning the challenge and immunity.

In, the challenge was again used for individual immunity. In this variation, players held onto a handle on a rope behind their backs, and a crank turned by Jeff Probst lowered the contestants face-first towards the water. Kim Spradlin won the challenge, and immunity.

This modified variation appeared again in at the Final 6. Dawn Meehan won the challenge, beating out Brenda Lowe.

The original version of the challenge reappeared the following season in. Monica Culpepper outlasted Tyson Apostol and Laura Morett to win her second Individual Immunity Challenge.
