How long does verification last? I'm just courious I have posted two runs over month ago now and they are still not verified. They are both over 40min long so there is nothing important but I just would like a verified run of mine.

Also can I now delete records of the runs? Or I have to wait until it gets verified?

According to your profile, you have yet to submit any runs.

If you do get runs verified, you need to keep the videos up permanently. Deleting the videos is grounds for the time being removed from the leaderboard.

@Pear the user has submitted 2 runs, they just haven't been verified. you can see this on the "info" tab

If you delete your runs they can be rejected, and there isn't really any reason to delete PBs at all. I'd keep them public. According to the moderation rules, mods have up to 3 weeks to verify runs, so if your runs haven't been verified in over a month, send a message to the game moderators and ask them to verify your run.

Verification usually doesn't take long. As @Pear pointed out, need to keep the vids up to be recognised
