You randomly generate a course with all filters on and try to get the fastest time. It has to always be random. Like Minecraft speed runs you load up a randomly generated world every time, like that but in grid runners pro. :D Pls add this as a speedrun catagory. :D THX

And you could and there would be different types with in the run being just hard, just medium, just easy, and all selected. But the only options you have to change are the levels of hardness.
