This map is very hard.

You have to go the left at start and keep close to the wall to gather speed, then jump and land on the other ramp ahead. If you lose speed (dont land smooth) you can still keep driving. The jump in the first checkpoint is quite easy, but there is a cut. Going to the next checkpoint, you can also do a cut (not really, I fixed it). Use the double boosters, then over the engine-off block and jump to the finish. (If you are too slow you must respawn/reset your run).
