I’d like to speedrun Mobil 1 Rally Championship but I’m not sure why there aren’t any level runs. The time trial mode in the game is basically perfect for speedrunning individual tracks so I can’t see why it shouldn’t make its way here.

Indeed, but you have to understand that no one else but me has run the game, so I didn't see it necessary to set everything up :)

I'll get around to doing it at some point.

I agree that it's not necessary to add individual stages to the Speedrun.com page...

...when they're all here already: https://rc2000.forumotion.com/t11-rc2000-ladder-drabina-rc2000
