Tour de France: Chris Froome saddened by doping allegations

Tour de France dominant leader Chris Froome of Team Sky has admitted he is quite frustrated at constant questions about doping following his exceptional performances in the 100th edition of the most famous cycling race in the world. Froome extended his advantage in the general classification with an amazing ride on Sunday but that brought him even more doping questions on Monday's rest day. Froome said: "It's sad that we're sitting here the day after the biggest victory of my life talking about doping." Team Sky boss Sir Dave Brailsford said he is prepared to give the World Anti-Doping Agency (Wada) all his team's data in an attempt to clarify any suspicions. Froome, aged 28, increased his lead to four minutes 14 seconds in winning Stage 15 on Mont Ventoux on Sunday but his success has not been acclaimed by most people around the race, despite Froome and Brailsford insisting that Sky are riding clean. Froome said on Monday: "My team-mates and I have been away from home for months training together and working hard to get here, we've slept on volcanoes to get ready for this, and here I am accused of being a cheat and a liar. That's not cool." In light of Lance Armstrong's admission earlier this year that he used performance-enhancing substances throughout his seven successive Tour de France victories from 1999 to 2005, some journalists made an obvious comparison between Froome and the American rider. "Lance cheated," Froome replied. "I'm not cheating. End of story." Froome added: "I can understand why people are asking about doping, given the history of the sport - they have been let down so many times before. But I'm also one of those people who's been let down. I've also believed in people who have turned out to be cheats and liars. But I can assure you, I'm not." Unless something really out of the ordinary happens Chris Froome will win this year's Tour de France, so Bet365 have set up an option to bet on who will finish second behind Froome in the general classification. Here are the odds: Alberto Contador - 5/6 Nairo Quintana - 11/5 Bauke Mollema - 9/2 Roman Kreuziger - 9/1 Laurens Ten Dam - 40/1
