British swimmer and 2024 Olympic silver medallist Ben Proud will compete in the 2026 Enhanced Games. But what are they?

The multi-sport Enhanced Games will allow athletes to use performance-enhancing substances without being subject to drug tests.

Those behind the proposal claim it will be the ‘Olympics of the future’, allowing athletes to take drugs in a bid to break ‘world records’.

Founder Aron D’Souza believes athletes should be entitled to do what they wish with their own bodies.

But the Australian businessman’s concept has been heavily criticised for the potential impact on athletes’ health, and undermining fair play.

UK Anti-Doping (Ukad) said last year its mission was “to protect sport from doping cheats”. It added: “There is no place in sport for performance-enhancing drugs, nor the Enhanced Games.”

At a launch event on Wednesday, Las Vegas was announced as the host of the inaugural Enhanced Games, which will run from 21-24 May 2026.

Organisers said that under their permitted conditions, Greek swimmer Kristian Gkolomeev had gone quicker than the 50m freestyle world record, which has stood since 2009.
