Provide Race Reviews 

There are several sites that offer the ability to provide race reviews and commentary including individual race websites. 

BibRave allows you to rate races on several factors such as race organization, difficulty of the course, things to do in the area, swag received at the race etc.   

Here are other racing websites where you can provide and/or learn about race ratings from other runners:
