Here is one more track for the Offroad Rally pack. I didn't post it with the first batch because the route is quite difficult to follow. I think I have worked out a system with the flags that will guide you around the track. Pass each color twice. Starting at the top left it's blue,orange,red & purple.
The Lightning does well here and a mix of Lightning and Rally is a good race. As the pack spreads out you will encounter opposing traffic on the east-west section. If you miss a pit stop you can just circle the bottom-left hills right back to the pits and the lap will still count.
