I gave it a go. This is the first layout I tried to make for someone. It looked like a good track so I thought I'd try it. It's not exactly like the picture but close enough. I didn't use the red/white barriers for obvious reasons. I used LYTe to make this layout. Great program btw RayOK!
I also added a figure 8 near the pits just for fun, see attached screenshot. If you don't like it you can always remove it.
