Drive up the wall in the tunnel without a floor (left). Remember to use the Riddler Access Code to manipulate the red and white blocks (right).

Remember that you’ll need to use the Riddler Access Code to flip between activating the red and green platforms/panels/walls. In the midst of the first tunnel, the floor will give way and as such you need to drive up the walls until there is solid ground below once again.

As with the other races, use the Afterburner whenever you are on straights and use the drift whilst going around corners, this will not only help you turn better, it will also slow down the timer as well which by the end of the challenge will shave about a second or two total off the time.
