I want to speedrun Minecraft Bedrock any% glitchless. Is it a good idea to do so? It would be my first official speedrun and I think it's easy enough to do. If so, are there any important tips I should be aware of?

You need to discuss any questions with the Minecraft community for that game. The main series forums can be found here: https://www.speedrun.com/mc/forum

you can try, but make sure to post in the mc forum (like Timmiluvs said) do it if you wanna, if you think you can.

If you enjoy the game, try and speedrun it, goodluck! And I believe in you
