Before we begin, a question: do you like your job? Never mind for a moment about the money or the benefits package or the staff discount or the manifold opportunities to pilfer stationery. Do you actually enjoy doing it? And if not, why not?
To Peter Sagan, then, the 26-year-old from Slovakia who won his second consecutive world championship on Sunday. Sagan has a fair claim to being one of the most compelling sporting figures in the world right now: a man redefining an entire era around not just his monstrous talents, but his inimitable personality.
We need not waste time listing his achievements: you can look them up if you want. Suffice to say that Sagan can win a bike race in more different ways than anybody else, and will continue winning bike races for as long as he can be bothered to do so.
No, the bare facts of Sagan's career are far less interesting than the manner in which he has gone about it. He launches outrageous attacks. He crosses the line doing wheelies. He skips a winnable Olympic road race in order to enter the mountain bike event, a discipline in which he has not competed seriously since he was a teenager. He becomes world champion for the first time, and devotes the first answer of his post-race interview to the European migrant crisis.
Earlier this year, Sagan was embroiled in a vaguely ridiculous micro-furore when he refused to honour the ritual of shaving his legs. You probably had to be over familiar with cycling's curious mores to gauge the true significance of this. Cyclists have been shaving their legs for more than a century. And yet here was Sagan, leg hairs dancing in the wind, gently toying with the sport's conventions and earning himself a good deal of criticism in the process. "Who came with this style?" he retorted. "Nobody knows, and yet everybody is shaving their legs."
