When Usain Bolt crosses the 100m finish line at this weekend's world championships, inevitably flashing a smile as large as his winning margin, his legacy as one of the world's greatest athletes will seem undeniable.
Bolt will head into retirement with eight Olympic gold medals, 11 wins at the world championships (plus whatever he can add in the next week) and a couple of almost unbeatable records. He will leave a significant hole in the athletics world and, for some time, represent the level to which budding sprinters aspire.
And inevitably in some cynical corners of the sporting world, Bolt will exit competition with a trace of suspicion that mars an otherwise unimpeachable career.
Is it fair that, due to the extent of his dominance, a fair few will remain wary of elevating Bolt to legendary status, considering over the course of his career he's never failed a doping test and any perceived guilt can be adjudged only by association? Probably not.
But will that change the view of a segment of the sporting fanbase, those who have previously been burned by believing the hype and are now unwilling to subscribe to fairytales based on outstanding sporting achievement? Definitely not.
