Should get done eventually, just remember that this is a pretty active speedrunning community so they need to deal with a lot of requests :)

Love it. Very easy to get into: Very short so you can speedrun it when you only have 1 or 2 minutes, and it doesn't have any complex glitches you have to memorize.

You can go to https://www.speedrun.com/pendingactions, then click on the run you want to remove, then click the settings below the video (three dots in a vertical line), then press Delete Run
