if you google 5k and your city name you will find some, but also you will find some sites that list them. active.com lists a lot around me, but there are several others too. there are still a number of 5ks that are not listed online though, so a trip to your local running store may be useful. they often have posters and pamphlets from 5ks in the area. The gnc near me does also.

Another vote for runningintheusa.com. I've found lots of races that way, and it's easy to filter by distance. I've also found them by checking out people's shirts at races I do--lots of times they're wearing shirts they got at other races. :)
