Tips:

• First, do a flip at the start to save time.
• Second, once pushing the weird boot thing down, do an in-the-air boost to be able to do a front flip onto a javelin.
• Third, do a backflip or frontflip on the weird thing that shoots a spikey ball out.
• Fourth, while in the air, do a boost.
• Fifth, use this boost, to fly across the boat of spikes.
• Sixth, front flip onto the thing and kill yourself to get to the finish line.
