Place one ramp under the backboard almost lined up with it, but slightly in 
front of it. Throw away the other ramp. When you start the challenge, go left 
and up the concrete until you reach the tunnel. Place the set marker as far as 
possible without leaving the challenge area. Skate as fast as possible towards 
the ramp. Hold R1 before hitting the ramp, and it should grab the backboard. Do 
not ollie. Hold that button and press Up as soon as you hit the ramp. Keep 
holding Up until after the handplant. Try adjusting the position of the ramp as 
needed.
