L'arriviste said:If it's anything like Oktos-Cofidis (the lovely cathedral town of St Quentin - a bit off the beaten track too) - and this is pure conjecture, of course - the action could centre on an amateur-feeder club (of which there are one or two main ones in that region, I think) that supplies up through the pros.
Just as a gut feeling it seems very unlikely to me that major teams based in the South are running a team doping programme out of Caen. If they had such a programme, there are surely more convenient places for them to be operating it.
But the coverage so far suggests both amateur and professional cyclists. So perhaps its an element of the local amateur scene combined with a pro or two who lives in the region?
I suppose we'll find out in the near future.
