The biggest race in the world? The 24 Hours of Le Mans is this weekend.

One of motorsport's three biggest races takes place this weekend in France. It is the annual 24 Hours of Le Mans, an endurance race that, together with the Indianapolis 500 and the Monaco Grand Prix, make up the 'triple crown,' an unofficial achievement that only the late Graham Hill can claim to have won. This year, 62 different cars take the start, racing on a mix of permanent race track but also public roads that for the rest of the year are how locals get to the supermarket or the local McDos. It's not the oldest race in the world, but it's up there—it was first held in 1923, and this year will be the 94th running. It was started as a way to give the automotive industry a grueling test for their new machinery and has remained the area of motorsport with the most road relevance. Disc brakes crossed over from aerospace to road cars at Le Mans, and better brakes continue to be tested there today, but it's also where companies like Porsche and Audi and Toyota proved new hybrid technology, brake-by-wire systems, direct-injection engines, and advanced headlights, to name but a few. This year, the 62 cars are split across three different classes, each crewed by three drivers who take shifts at the wheel. Some of the drivers are pros—among the world's very best. But plenty are amateurs; in the past, lots of dentists, oddly enough. But with the cost of racing these days, it's the tech bros. The Ruby on Rails creator, the co-founder of GitHub, and the co-founder of Crowdstrike are all racing in the LMP2 class. And Valve's Gabe Newell owns the Aston Martin team that is competing in both Hypercar—with the outrageous-looking and -sounding Valkyrie—as well as in LMGT3, where his son Gray will be one of the drivers.
