Maplewood has a 4th of July 5K! The website info is from last year, but I'm assuming it'll be updated as the date gets closer:

There are a couple of sites out there that have running calendars, i have been using this one recently: http://www.runningintheusa.com/Default.aspx
Bridges run is next weekend near McLoons boat house- great causes- scholarships for east orange, Orange, Newark etc boys to Seton Hall Prep. A really nice group and a lovely run.
Oops just reread and saw you are looking for July. Sorry
I haven't run in forever, but think I need a 5K to get myself motivated. I am looking for a gentle (aka easy) 2 mile to 5K run in July. Hoping someone can provide suggestions for a slooooow runner.
Thanks!
