Does anyone know/is there any way to find out what the longest verified run on this site is? I'm also interested in the longest WR on the site.
longest wr is https://www.speedrun.com/srotsm#No_Time_Manipulation debatably
Another very long World Record is Baten Kaitos: Eternal Wings and the Lost Ocean 100% with 338h 43m which is roughly two weeks.
Here are 5 long speedruns I've seen on the site. Some of these runs aren't WRs but they're still very long.
