This is the unchanged Obstacle Cruise, just with a changed grid point, now the Obstacle raceway.

If you start with Quickrace follow the path up to Checkpoint eight and cross before the gate this little border up on the long rally track. 

After reaching this point you can see at the mini selection picture the end, Checkpint eight will come soon cross it and go to finish line then you do have the time. 

I still needed 12 minutes minimum.

I first tried to make a tar road through the Obstacle park, but the editor stopped me, to much textures, so I used the original ones  with the bridges from construction junction.

If you can make diagonales on tar, please do me a faver and make a long Highway from my route.

Have fun.
