I think races, for people who organize them are quite specific and done for one reason or another. By what I can see now there are quite a few new ones popping up. Believe in your product and understand it will take time to grow. Be involved and show passion. For me that is a winning formula. Again just my thoughts. While the hub is a cycling website there are a ton of cyclists out there. Quite a lot have never been on this site. It is a rapidly growing sport. From what I am seeing, price and value for money are key points. Keep your idea. It seems your passion is good.
