There are at least 5 shortcuts in this track.
1. There is one just before the start, turn right after orange fence and do a jump,

2. On the right side of the track after the sign.
3. Keep left after the sign and go to the left of the rocks for a speed climb up !
4. Instead of going on the grey track go on the left side, you can go much faster !
5. At the end of the grey track you can jump over the hill and not get the red X.
The lap time should be around 36.5 to 37 seconds, with the shortcuts its at 32 or lower !
The last time trial lap time I got was 27.9 seconds. I started from the flat green ground to the right of the track at the start.
And there are no pickups.
