Great Wall

Modified obstacle. This is the Warped Wall, a foot taller and with a large overhang at the top. Contestants run up the wall, grab a rope hanging from the top, and climb over.

The added height makes the wall more of a challenge, but the overhang and rope mean they can only climb up in one tiny place. So most of the obstacle is wasted space. I didn't like the Curved Wall in previous seasons for the same reason.
