Over a period of nearly four months, he has chalked up air miles many would have thought impossible.
He has also walked a lot. And run a lot.
And talked a lot.
At meeting after meeting, at events and interviews all over the world, over the radio, TV, in newspapers, magazines and in cyberspace, Ng Ser Miang has discussed his ideas of how he would shape the world of sport.
Remarkably, the Singaporean, one of six men in the race to succeed Jacques Rogge as president of the International Olympic Committee (IOC), says he's not tired.
I spoke to him yesterday soon after the IOC entrusted Tokyo with the 2020 Olympic Games.
It was 11pm Saturday in Buenos Aires, there were about 2½ days left before the new IOC president would be revealed, and the hottest name in Singapore sport over the last couple of weeks sounded fresh and strong.
The 64-year-old, who has been in the Argentine capital for around a week for the 125th IOC Session, said: "We've had executive board meetings over four days now and they've been heavy days.
"There's been lots of meetings and always, the agenda of the day takes over.
"It's been long days," Ng admitted.
He officially threw his hat in the ring in May, and today, the IOC vice-president will make his final push to convince 103 of his colleagues that he is the right man to lead the movement after Rogge.
So will the other five candidates, before the winner is announced tomorrow.
