It's the biggest weekend in racing, so what are you planning to watch?

As we prepare to head into Memorial Day weekend, there's a bumper crop of wheel-to-wheel action on offer for the motorsports fan*. Both IndyCar and Formula 1 have their biggest races of the year this Sunday, NASCAR has its 600-mile race at Charlotte, and over in Germany hundreds of thousands of fans are camping around (and possibly setting fire to) the mighty Nürburgring.

Despite not being broadcast here in the US, the last of these is probably the easiest for you to watch. That's because the organizers have provided a free International livestream on YouTube:

The race starts at 11am ET (3pm CET) on Saturday (May 27) and runs for the next 24 hours. There's also English language commentary from the always-excellent team at Radio Le Mans.

Meanwhile, about 650 miles (1050km) southwest of the 'Ring, Formula 1 has made its annual pilgrimage to that sunny place for shady people: the Principality of Monaco. Grand Prix races have been held around the streets of this little fishing village-cum-tax haven since 1929, predating the Formula 1 World Championship by two decades. A notoriously difficult track on which to overtake, the winner will almost certainly be whomever manages to snag pole position on Saturday. You can watch that on NBC Sports on Saturday morning at 8am ET, and the race will be broadcast live Sunday morning on NBC at 7:30am ET.

But wait, there's more!

Over here in the US, the IndyCar series is running its crown jewel, the Indianapolis 500 on Sunday. It's the 101st running of the race, and any fears of a post-centenary dip in interest was allayed thanks to a Mr. Alonso. That's right, one of Formula 1's very biggest stars has decided to pass on running an uncompetitive race in his McLaren for a chance to earn the Triple Crown—winning the Monaco Grand Prix (which he did in 2006 and 2007), the Indy 500, and the 24 Hours of Le Mans. A YouTube livestream of his first practice laps at Indy earlier in the month drew more than two million viewers, a pretty impressive feat.
Alonso will start from a very credible 5th place on the grid, and Scott Dixon grabbed pole with a four-lap average speed of 232.164mph (373.631km/h). Qualifying—which took place last week—was marred by Sebastien Bourdais' horrific high-speed crash at Turn 2. Hitting the wall at 227mph (365km/h), he ended up with hip and pelvis fractures that will have him sidelined from the race (as well as Le Mans next month). Bourdais was just released from hospital, and we wish him a very speedy recovery.

The Indy 500 will be broadcast on ABC on Sunday, May 28 at 11am ET.

Just in case almost 30 hours of racing isn't quite enough, NASCAR is holding an even longer oval race this weekend: the Coca-Cola 600 at Charlotte Motor Speedway in North Carolina. Sadly no driver is attempting to run both Indy and Charlotte this year, unlike Kurt Busch in 2014. As with Monaco and Indy, Charlotte will be broadcast on network TV—Fox in this case—at 6pm ET on Sunday.
Now if you'll excuse me, I think it's time to stock the fridge.
