I need sincere and frank advice from you guys. I'm involved in running the AHRMA "Post-Vintage" races in Northern California and we just can't seem to grow the sport for bikes of this era. The Vintage bikes draw between 200-300 entries on a regular basis, but we never seem to crack the 100 entry mark (sometime less than 60). I have racked my brain for the last few years trying to figure out how to improve these numbers for post-75, pre-85 bikes.
AHRMA Vintage is large enough to fill a whole day and the long-travel bikes get the second day by themselves. Needless to say only 60 entries is hard for any promoter to swallow (covers costs only). I have started a website, left flyers in bikes shops around Northern Cal, we have had races with Modern Bike Vet groups and had many people talk to us about our bikes, but no takers yet. We have even offered to lone our bikes to people on many occasions.
How did your organizations get high levels of participation for the post-75, pre-85 bikes?
