if you go to the page for the specific speedrun youre looking for I.E. DLC any% Regular below the difficulty theres an option that says show rules. Once you open that at the top of the rules theres 2 options Game Rules and Category Rules. Im guessing youre looking for category specifically it'll be the one on the right.
