Christian shoots himself in the foot
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Christian starts off well, immediately taking off one of his shoes to mark his starting position. Once his blindfold is removed, he very quickly spots his shoe and is able to return to his exact starting point. However, it is revealed in the studio that he also (for some reason) tampered with the GPS device, erasing its data. He is therefore assigned distances of 0m travelled, 0m returned, and 0m away from the starting point, giving a balance of 0m and scoring him last place.
