Dunno who this is, but the positive test is for the same diuretic that Kolobnev was done for during the 2011 TdF – he was eventually cleared of intentional doping due to traces of the drug being found in an over-the-counter medecine that he’s been recommended by his doctor.
Hopefully the FFC have seen evidence to suggest that the positive test is from this type of contamination and that’s why they’ve handed down a minimum ban.
However, without anything to support this it’s just as easy to start getting outraged and fire up the pitchforks.
Regarding race organisers, I think that if races are sanctioned by the national federations then they have to abide by the WADA code, so they can’t impose extra punishments on riders who have served their ban (similar to what overturned the team GB/BC ban on former dopers).
It’s a different story for non-sanctioned races, they can do what they want. To be honest I thought that the Megavalanches were unsanctioned!
