At the BMX finals, the stands were packed with cheering fans who sat in the searing heat to watch races that took less than 40 seconds to complete. This was Olympic street cred in spades. France’s Anne-Caroline Chausson, gold medallist in the women’s BMX, said: “This is a warrior sport. There’s eight people confronting each other and the best wins”. Men’s bronze medallist Donny Robinson of the US said: “Kids think it’s cool and parents know we are good role models”.
