Meanwhile, the Professional Cyclists' Association (CPA) has issued a statement in support of Froome and his fellow riders against unsubstantiated doping rumours.
voiced his frustration at continued questions about doping,
and Team Sky boss Sir Dave Brailsford is prepared to give the World Anti-Doping Agency (Wada) all of his team's data in an attempt to allay suspicions.
"It's not fair to blame someone without evidence against him and we demand more respect for Chris and for all the riders," said CPA president Gianni Bugno.
"We are witnessing a daily attack against the dignity of the riders in a manner that can no longer be tolerated.
"The CPA, who has always supported the importance of the fight against doping, condemn, however, the fury of media and institutions which over the years has often led to the association that cycling equals doping."
The CPA added professional riders were "the most controlled athletes in the world" and "too often portrayed as dishonest".
