I never understood why people would want to speedrun the game on release. That's something you start doing after doing every quest in the game and generally haven't got much left to do. By speedrunning it on release, not only will you essentially ruin all the exploration, you'll miss the story, the character interaction and so on, only to find out that your time is beaten fairly quickly. Why? Well, not only will someone nearly always do it faster by virtue of some shortcut you don't know of yet, you'll also be painfully slow by definition as you don't know a damn thing about the game you try to speedrun. I've done speedruns back in the day and it's god damn hard work to do it right. Doing a speedrun on the first try doesn't just ruin your experience, it's borderline insulting as you've put no effort into it though knowledge of glitches, exploits, useful spells/shouts and so on.
