I am hosting a new speedrun marathon called Racing Games + Speedruns = Spectacular! In case you couldn't tell from the title, it is a marathon that focuses on speedruns in racing games! If you want to come do a full-game run, then submissions are going on now! Go to the link and submit a run! Or you can also help spread the news around to other people
