Doping Testing ...
It should also be said that ALL races in Flanders are subject to POSSIBLE dope testing, including amateur races. So it is important to stay till the end of the race to check if the large yellow doping bus shows up (or any other doping agency). There will be an official list posted on the truck and at the start finish with the listed riders. Be sure to show up with your passport and racing license. You are also allowed to have a team director accompany you.
