Chris Froome: 'Athletics must invest in anti-doping'

Chris Froome has said that doping allegations within athletics will only become a thing of the past if the sport invests in measures to prevent competitors from using performance-enhancing drugs.

In 2015, athletics has been hit by several doping scandals ahead of the World Championships, which take place in Beijing later this month, and Froome has insisted that the sport will only be perceived in a better light should athletics follow cycling in installing new methods to catch drug cheats.

The 30-year-old told BBC Sport: "From what I understand, the testing hasn't been at the level that it is in cycling. It is going to have to invest a lot more heavily in anti-doping. That would be a step in the right direction."

In July, Froome won his second Tour de France title but throughout the race, he came under the spotlight after the eligibility of his performances were doubted as he dominated his rivals during the toughest mountain stages.
