I might be relocating to Harlem from South Florida. Where can I find information on road races going on in the area? What is the NYC equivalent of floridacycling.com?

You can start with these two -

Nyvelocity.com

NYCC.ORG never hurts, plenty of Racers there also and you can find plenty of
fast weekend rides.
