2 × 122m “Dread the Tread” – new for 2022!

2 × competitors in a mixed team, each swimming 2 × 61m lengths.

Both swimmers must enter the water and stay in the water until they have both finished their swims.

Both swimmers must tread water as they wait, no touching the wall or lane rope.

Start – first swimmer holds wall with one hand, second swimmer treads water and touches nothing as their teammate swims two lengths.

Takeover – second swimmer can only hold the wall once the first swimmer enters the 5m red zone and starts after the first swimmer touches the wall.

Continuation – first swimmer must then let go of wall immediately and tread water without touching anything as their teammate completes two lengths.

Finish – when the second swimmer reaches the wall, then both swimmers can exit the water.
