I had a hell of a time with that one too. I finally got it by doing the long jumps over the two long stretches to the right side of the grid (from where you start). If you successfully get across the first "bridge" and then turn right around and get the other one on the way back, you're halfway to the finish right there. From there, it's just a lot of turning and jumping and leaving yourself a path back to the gold star. You can do it! Check out youtube for a video if you need to.
