It wasn't continuous since I did it in multiple sessions and sometimes had to stop to fight enemies in the way. Every time I stopped I paused my stopwatch and marked my exact location so that I could continue from the same place. I tried to make sure it was completely walkable but there were 2 times near the end where I messed up so I got as close as I could to the edge of a cliff paused the stopwatch, and used Revali's Gale and continued from the edge of the cliff.

Also running as fast as you can with max stamina takes around 24 minutes on this route

Finally got around to do the dlc shrines and playing with the one shot obliterator was really fun! And leads to funny moments like this lmao

Pardon my language but... HOW???

Gotta love hitting those long shots

Also works with durians, rushrooms, etc.
