TOKYO (Reuters) -David Howden, chairman of the Athletics Integrity Unit, says his organisation's anti-doping work is having a tangible impact on the sport and the evidence is to be seen in the wider range of countries winning medals at the World Championships.
The AIU was set up as an independent arm of World Athletics in 2017 following the Russian doping scandal and is seen by many as the benchmark across all sport for fighting the use of performance-enhancing drugs.
