im trying to speed run one track were do i submit that?

players page (time trials) on the left of the website

Or mkleaderboards. That's where I submit lol.

mariokartplayers.com/mk8
mkleaderboards.com
Sign up and submit your best time trials records!
You get your own player page and your times show up on the site's leaderboards.

Yeah that's why there's no IL. Because we've had mariokartplayers.com for a long time and mkleaderboards.com too.

Also if you want to see the world records for the tracks, there's mkwrs.com. They also show past world records.

I got a time of 1:18.100 om big blue in mariokart 8 deluxe. Where to post it?
