You will start from the top end of the race track, outside of the cloud (image 1)
Go straight (image 2) and then you will see tracks leading down and you will go through those (image 3)
At the end of the spiral, you have to make a sharp turn and keep going forwards where it is pointing (image 4)
Go around the OUTER loop and then head straight. You will then encounter an intersection and you will have to make a sharp turn RIGHT (image 5)
You will know you are going in the right direction becasue the race track infront of you will start going upwards. (image 6). Instead of that, turn right again.
remember that sharp turn after the spiral? That is your marker indicating you finished a lap! (image 7)
To make a repair stop, enter the shorter loop and not the outer loop (image 8 and 9)
When finished all laps, go straight to the end! (image 10 and 11)
