Kristoffer barely moves
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Kristoffer also declines the safety helmet, and decides he wants to ride forwards with the office chair facing backwards. However, he does not request enough power from Olli, for his weight, barely rolling any distance at all. Apparently disappointed that his missed his opportunity to use the crash mat, he runs and throws himself on it, as Atle tries to close the segment. He earns third place for his effort.
