I'm going to be attempting some VR speedruns, and I don't know where I'd submit them, if there's even a place for it at all. Honestly I just thought it'd be a funny idea but it would be cool if there's a genuine place to submit VR runs around

Depends on the game. VR runs in Bedrock edition are allowed as per https://git.mcbe.wtf/MCBE-Speedrunning/Speedrunning-Rulebook/src/branch/master/platform_rules/README.md#virtual-reality

I dont think you can submit a vr speedrun but if you can that would be funny
