Stop halfway over the arrow
	End up in the water
	The prodding bar

There is a board at the end of a long runway. The contestant has to run up and jump on the board to slide along. The aim is to end up stopping with the arrow in the middle of their board aligned exactly with an arrow at the end of the runway.
If the contestant pushes off too hard they'll slide straight off the end, into the water below. If they don't push off hard enough they won't reach the arrow, will come up short, and will be pushed off into the water by a lurking Guard.
As an extra difficulty, half way down the runway is a bar being pushed in and out over the runway, which may block or knock off the contestant if they're unlucky.
