Since 2012 it has become increasingly clear that Peter Sagan is, as the French would say, un cas à part – in a class of his Branden Albert Womens Jersey own. In sporting terms, the double world champion appears utterly impervious to pressure and can prove utterly unbeatable on his day, as was the case here in a carbon copy of his victory last year in Cherbourg. It is also true in terms of the image he projects.Cycling has never seen anyone quite like the Slovak, whose strength cannot be matched in this kind of uphill finish, rising just under 100 metres in two kilometres, after a five-hour slog south, mainly into a headwind. At 300 metres to go, as he wound up for the sprint against Michael Matthews, Greg Van Avermaet, Daniel Martin and Arnaud Démare – all names to be reckoned with on their day – the cleat on his right shoe detached itself from his clipless pedal.In a flash the Slovak had to fish around with his foot to put it back in the pedal, losing momentum as he did so. He was stalled for less than a second but that should have been more than enough to wreck his chances.The new study will not stop Semenya and other hyperandrogenic athletes, such as the Indian sprinter Dutee Chand, from competing at the world championships in London in August but it could have a significant impact on the Cas hearing later this month.It is bound to reopen the controversial and emotionally charged debate around the treatment of female athletes with hyperandrogenism, a medical condition characterised by excessive levels of male sex hormones such as testosterone.Researchers measured blood testosterone levels in 1,332 female athletes competing across 21 track and field disciplines at the 2011 and 2013 world championships. Those with the highest levels of testosterone demonstrated significant advantages over those with the lowest Reilly Smith Authentic Jersey levels – notably in the 400m (2.7% faster), the 400m hurdles (2.8% faster), the 800m (1.8% faster), the hammer throw (4.5% longer) and in the pole vault (2.9% higher).Although these margins appear small, at the highest level a performance boost of a few percentage points might mean the difference between winning gold and missing out on a medal.Stéphane Bermon led the research from the Monaco Institute of Sports Medicine and Surgery, together with Dr Pierre-Yves Garnier, director of the IAAF health and science department. Bermon said: “This study brings new evidence [of] the performance-enhancing effects of androgens in elite female athletes. Although long suspected [to be the case], until now there was no proof.As cycling’s only champion with serious internet and youth appeal, combined with his ability on the bike, he was last year’s transfer prize and he opted to become the centre of a revamped Bora–Hansgrohe team, which he leads with the Pole Rafal Majka. Being his own master rather than banging heads constantly with his previous Mark Barron Youth Jersey boss, the Russian Oleg Tinkov, clearly suits him. From being odds-on to take a sixth green jersey that now looks as close to a certainty as anything on two wheels can be.Testosterone has several potential performance-enhancing effects on the body, including boosting the oxygen-carrying capacity of the blood, building lean muscle mass and increasing mental drive and aggressiveness. The new study also found that female competitors with high levels of androgens benefit from improved visuospatial abilities.Froome is equally far from being an Identikit champion. With little fanfare, the triple Tour winner is getting quietly on with his campaign; three days in, it is going to plan apart from any lingering effects of Sunday’s crash, which would have been expected to be felt here. He moved up the standings to second yesterday behind Geraint Thomas and he has an advantage over his opponents which is more than healthy.
