NJ Trail Series partners with Rick Reed at Cricket Hill for the Muddy Marathon in Rockaway NJ. It is the Saturday of the first weekend in May. This year it is actually April 30. The Muddy Marathon is a chance for anyone and everyone to get out on some trails and get filthy dirty and then relax with a cool craft brew and some tasty BBQ.
You can find more info at www.njtrailseries.com/muddy or just shoot Rick (not Reed, the guy who runs the Muddy Marathon) an email. Rick says
I know a lot of craft beer drinkers also like to get outside and have fun so there probably is a lot of interest from your readers about the event.
