IAAF hits back at Chris Froome comments

Chris Froome’s claims that athletics should follow cycling’s lead and invest more heavily in anti-doping have been criticised by track and field’s global governing body.

The International Association of Athletics Federations insists it is already spending more than any other sport in the battle against drugs.

British cyclist Froome faced constant allegations and innuendo on his way to his second Tour de France victory last month, claims which were partially quietened when Team Sky released some of his power data midway through the race.
