I’m guessing Bolt is being made aware of the significance and difficulty of achieving the sprint treble in any area: Olympic titles, world records. I’m not even aware of any male having won all three titles at the Commonwealth Games level. The Aussie Raelene Boyle certainly achieved it at Commonwealth level, having won the 100/200 in 1970 and again in 1974 before winning 400m gold in 1982 in her farewell race.
And of course another Aussie - Betty Cuthbert - is the only person to have won gold at 100 and 200m (Melbourne 1956) and 400m (Tokyo 1964) in Olympic competition.
History continues to beckon Bolt…and he knows it. Great talent carries with it a (public) burden of expectations.
