Simon Gerrans has taken the yellow jersey of the Tour de France, 32 years after his first mentor Phil Anderson became the first Australian to do so. His South African teammate of Orica GreenEdge Daryl Impey is on the verge of succeeding to him and become the first-ever African cyclist to lead the world's biggest race the year that Kenyan-born Chris Froome was highly expected to be the one.
