Follow the dirt track route up to the first jump onto a large platform. From there you collect the first checkpoint, pass over the jump and turn right into the 270 degree turn before making the choice of whether to jump to the next checkpoint or just drive to it. You then collect the third checkpoint where you enter first person and drive up the right or left side of the ice where you land on the loop and drive down, through the fourth and final checkpoint, before heading round the ice turn and into the finish. Just a fun little track.
