Athletics has become the first sport to offer prize money to Olympic champions, announcing that the 48 gold medallists in Paris this year will earn $50,000 each to end a 128-year tradition.

Although the concept of purely amateur competition has long since disappeared from the modern Olympics with athletes often receiving payments from sponsors and professionals taking part for years, the World Athletics (WA) decision is a major shift.

WA President, Sebastian Coe, said there had been no discussion with the International Olympic Committee, only that his organisation had given the IOC a heads-up shortly before announcing the $2.4 million prize pot.

“While it is impossible to put a marketable value on winning an Olympic medal, or on the commitment and focus it takes to even represent your country at an Olympic Games, it is important we make sure some of the revenues generated by our athletes are directly returned to those who make the Games the global spectacle that it is,” Coe told reporters.

“I don’t believe this is remotely at variance with the concept that the IOC often talks about, which is recognising the efforts that our competitors make for the overall success of the Games.”

Norway’s Olympic 400m hurdles champion Karsten Warholm welcomed the news.

“I think it’s good so I want to salute them for it,” Warholm said in an interview. “It doesn’t change my motivation to win because for the Olympics I’m not in it for the money. The gold medal is worth a lot more to me personally.”

The IOC said it was up to each International Federation (IF) and National Olympic Committee (NOC) to determine how to best serve their athletes and the development of their sports.

“The IOC redistributes 90% of all its income, in particular to the NOCs and IFs. This means that, every day, the equivalent of $4.2 million goes to help athletes and sports organisations at all levels around the world,” the ruling body said.

A total of $540 million was allocated to the 28 sports at the Tokyo Games, with World Athletics receiving the most at $40 million.
