You can watch them piece by piece (meaning if its broken up by chapters like this), if its too long. I personally don’t do that, but can absolutely understand it. Nowadays I also watch most videos at higher speed. Some talk really slow, I mean slow that I watch it at x1.4 speed and it sounds like someone else is talking at x1.0 speed. But this video, I didn’t have a problem with the narration itself.
BTW I recommend Looking for an addon or like that if you watch on a browser. I have a more fine control over the speed values, as x1.25 sometimes is too fast. In example I often watch at x1.1 by default or sometimes at x1.2… and in really bad cases even faster.
