Door Knock

The Door Knock is an obstacle, used as the first obstacle in the Qualifier during episodes 3 and 11 of Season 3.

It is three doors that contestants must run up and choose to open one. However, behind every door stands a giant hammer that swings down and knocks them into the mud. If they somehow manage to dodge or withstand the blow of the hammer, they can go through the door and onto the next obstacle.

Only seven contestants cleared this obstacle:

Isaia Ofoia (3x03)
Amanda Raddatz (3x03)
Rene Thorn (3x03)
Tucker Carney (3x03)
Jason De Muro (3x11)
Kodie Elzie (3x11)
Frank Beasley (3x11)

Coincidentally, the latter later went on to win his respective episode.

Trivia[]

The Wipeout producers had a hard time designing the doors. They made these double doors, so contestants had to stand in the middle of them close to the doors with little chance of avoiding the impact.
The head of the hammer is two feet of foam. Behind the hammer, however, is a 5-inch thick metal pipe on a pendulum. You can't even lift it.
In Wipeout: The Game, the Door Knock functions differently in that players must run past the three doors with hammers coming out randomly.
A similar obstacle named the Door Knockers later appeared as the first obstacle in the Qualifier during episodes 2, 5, and 8 of Season 7 now with a different look and added features.
- The first door launches contestants forwards instead of backwards.
- Sometimes, the obstacle features toilets, pie, and chocolate cake.
