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 where you can talk about it all in one convenient place. Where else would you want to spend your weekend?

The big once-around-the-clock race on the terrible concrete track is back. I feel like we just did one of these, because it was postponed to the end of the 2020 season, so the most recent 12 Hours of Sebring was just last November. Hard to believe it was that recent. Anyway, let’s do it again, shall we? Oh, and there’s NASCAR action in Atlanta, and Aussie Supercars at Sandown. Plenty of action all around.
