The Chinese Grand Prix - Formula 1's 1000th 'birthday' - is no more or less important than the one in Bahrain that preceded it or the one in Baku that follows. But while the 1000th world championship race has no greater intrinsic value than the other 999, it does have a wider significance that makes it worth celebrating.
Because we have a combined total of 10 fingers and thumbs and therefore created a base 10 mathematical system, 1000 is a nice round number and people can't help but enjoy celebrating such milestones. And it's worth marking as a remarkable feat of endurance, one that has defined motorsport for the past 70 years.
But what Autosport has dubbed 'F1 1000' and a celebration of the 1000th GP is a landmark laden with semantic troubles. China will be the 1000th world championship race, but only the 974th race you can append 'Formula 1' to in a literal sense. There were 11 Indianapolis 500s that counted for points from 1950 to 1960, which were not F1 races, while a total of 15 world championship races were run to F2 regulations in 1952 and 1953.
