Then do a speedrun where you don't do any "glitches" or "ultra-precise" tricks. Runs like 100 egg have less glitches so you can start there. You could even go to the category extension board and try any% ILE (intended level entries) which have even less "glitches". But you can just do runs without the glitches and have fun that way. Yeah it may not be a competitive time, but speedrunning is about beating your own time. Plus, once you practice a bit a lot of the "ultra-precise" tricks become very much not "ultra-precise", as do any tricks in any speedrunning category for any game. I would honestly just give it a shot and ask for advice from other runners on how to do some of the tricks, if you plan to do tricks at all, and see how you like the run.
