Christian alters the course
Christian starts with a fairly long pole, and seems to manage to get through the house with minimal errors.
It is not until he gets back outside that he has an idea: he will simply move the markers to make the course easier for himself.
Christian moves the markers from the canvas tunnel, the tyres, and the mailbox, allowing himself to completely bypass those obstacles and complete the course.
Having started with a 5.15 metre pole, Christian ultimately ends up with a 4.55 metre pole, after errors.
However, Mark then plays some additional footage that reveals that there was still a marker inside the mailbox which he had not spotted, meaning that it was still a part of the course. Christian is therefore disqualified for not completing the course.
