HADES Fleur Skip
From Horizon Speedrun Wiki
The HADES Fleur Skip was found on the 24th of March 2021 by Fleur_Bleue101. It takes place during the "The Face Of Extinction" main quest. By running up to a turn on the path to HADES, and then turning around right after passing some rocks sticking slightly out of the wall, you can jump up on the rocks and skip a small amount of movement. This saves about a second. Video of the skip:
