The stuff CTG legend is made of. You might just need the All-Spark Cube in your back pocket to successfully complete this elite obstacle. At first, this obstacle doesn’t seem all that difficult, but half way through the foot holds drop off and runners must span the structure using only their arms. With a peg in each hand, you must transform into lean, mean, pull up machine in order to traverse the gap. By sliding these pegs in and out of the holes on the wall you’ll make your way across without your feet touching the ground. This is THE most difficult CTG obstacle from a pure upper body strength perspective. Even Decepticons and Autobots would struggle to conquer this beast, so unless you’re made out of metal, you better start training NOW!
