Welcome to the Jalopnik Weekend Motorsports Roundup, where we let you know what's going on in the world of racing, where you can see it, and talk about it all in one convenient place. Where else would you want to spend your weekend?

Oh my God, you guys. THIS WEEKEND.

After months upon months of telling you "Well, there's nothing on this weekend except a World Endurance Championship race from last year and some drag racing, herp derp" I can finally say that there is some serious-ass racing on tap for a change!

What do we have? First, we have the 12 Hours of Sebring. That one's gonna be on Saturday, and it will be spread throughout the afternoon on SPEED and all day. If you haven't done so already, check out Porsche9146's spotter's guide so you can impress all your friends with your in-dept knowledge of all the cars.

Then! Then we have the first race of the 2013 Formula One season, baby! Even though it's on at the ungodly hour of 1:30 a.m. on Sunday, you will want to watch the Australian Grand Prix. It's the first time NBC has covered F1, so we're eager to see how they get it done. Admit it, you're not doing anything wholesome at that time anyway.

Wait. What's that you're saying? "I just don't think that's enough motherfuckin' racing for me, Patrick George! What should I do?" Well you're in luck because NASCAR is at Bristol this weekend, and that should make for a great show. And there's Australian V8 Supercars too. Anyone have a good livestream for that one? (Edit: .)

Who's not getting anything accomplished at all this weekend? You, that's who. Unless you count "watching racing and being awesome" as an accomplishment. In that case, you're golden.

As always, please let us know about anything we missed, as well as good livestreams, in the comments.

All times Eastern.
