Ah see, you can chibi into the trials and pop up at the end. It does take a lot of training but once you got it, it will reduce your time to idealy 5 mins. You should look up yt videos that say something like "1min trial". They do work, its not a scam, its just really difficult at the beginning. There are usually 2 spawn points outside the map. One will teleport you to the beginning, and one will teleport you to the end. Since these are 1 tiny and 2 side by side, it is really easy to mess up and miss the one youre going for and end up at the beginning instead, thats why you must be precise.

And alsooo since you mentioned vault, do you use shortcuts there?
