rookie question

[jkxw]

What exactly is a mass start race? what constitues a mass start race? I know now that I'm cat 5 I have to start in 10 mass start races to move up. Do my club races in central park (CRCA) count as mass start races?

The whole field starts at once. This is contrasted wth a time trial, where racers start one-by-one, or a handicapped race, where one category is given a headstart on another category.
