Pod Racer Walkthrough: 3: Gauntlet
This starts out the same as the last race - go into a tube on the surface. Gun it in the tube, then go straight across the tops of the various sand areas, still gunning it. Dodge the sand people's shots, heading towards the moon while you can. At the wall, gun it and head right into the canyons and another tube. There'll be two curves, down a tunnel, through a rotating door, and into a gravity tunnel. Really, it should be pretty easy after everything else you've overcome!
