Initiate a super boost from the start. initiate a wide red drift into turn 1 slightly after you exit the barn. Release the drift at the start of the speed bumps. Attempt to time your hops so that you catch as little airtime as possible. As you may know, traction and time are inversely proportionate in racing. Try to aim for the left hand side of the bridge, the geometry of a right angle can give you a reliable boost of speed, but be careful not to fall off.

After the bridge, initiate a drift and take the path on the right. Release this drift and initiate another once you exit turn 4. At this point, you will be around the area where you need to pull off some tech. You must aim your kart at the edge of a rock near the fence at the hairpin turn. You can launch yourself off the rock and over the fence, saving around 14 seconds if you pull it off twice in a race. This is the difference between winning and losing right here folks.

Alternatively, you can try to avoid breaking the game and do it like this:

Boost through the corners, modulate your brakes, carry as much speed as you can. If you're not getting sore in your hand after playing, you are not playing hard enough. See the below video for my personal best time.
