Back in 1998, the Festina cycling team's soigneur was caught with a car trunk full of PEDs including EPO, steroids etc, This was enough to get the Festina team banned from the Tour de France. They protested that none of their riders had tested positive but the circumstantial evidence was there and good enough for the governing bodies to take action. Later, after interrogation by French judicial authorities, many of the Festina riders did confess that they had been using PEDs to compete in cycling.
It is obvious that Aden's training group have been doping and they should not be allowed to compete in Rio. This site should not really be covering the T and F events in Rio as the authorities are obviously turning a blind eye to PED use in T and F, possibly as a result of a fair amount of cash being paid to the powers that be if previous events are anything to go by.
