PBP allegedly has testing. Never seen it happen, but I have never been far away from the back of the field.
I had to throw away the medicine I'd bought in France the previous year (for a sore throat) and buy something much less effective.
When Marie-George Buffet brought in widespread testing following the Festina case the FFCT and cycle-touring events were included in the action. I have never seen or heard of drug-testing in any FFCT event but it would not be unreasonable to expect it in events like the BRA (or PBP). The bigger problem, apart from how it is paid for, is what possible sanction could be imposed, bearing in mind that you don't even need to have a licence from one of the federations to take part in these events and that checking the names of potentially barred riders could be very difficult. Taken further, do you ban someone from riding his bike to work after a doping offence? No licence needed! All of which means that it is unlikely to happen even in events like sportives where there is a proven need for testing.
