The Tour de France is just around the corner, and the riders are in the final stages of their preparations. This includes Chris Froome, who will be defending his title this year. He recently took to Twitter to publicly complain about the irregular doping controls, which he believes are essential, especially just before such an important race. "Three Tour favorites are training in Tenerife, and in two and a half weeks, none of them will be tested – that's very disappointing ," the Sky rider stated. He, along with Vincenzo Nibali and Alberto Contador, is currently preparing for the three-week race on Spain's highest mountain. "I just think it's in all of our best interests to prove we're clean ," Froome added.
