www.belgiancyclingselection.be has a full list of all NON-UCI events and they are open to anyone. It does include the wielerbondvlaanderen (belgian cycling federation) races as well. First click on Kalender Veldrijden, then click on the month. Once you find a race you like, go to the links tab and look for the organization under wielerbonden.
Christine, thanks for the info.
So... it looks like the only categories are age based? Looks like I am a "B" if born in 1978, did I get that right?
On the Kalender there are races that specify category: "a-b-c', what about the ones that list "NA" what does that mean?
