I don't live around Norwood but Harriman and Bear Mountain State Parks in New York are less than 30 minutes north from Norwood on the Pallisades Interstate Parkway. 100s of miles of trails, lots of single-track with enough rocks, roots, and steep climbs to keep you busy for quite some time. Trail maps are available from Campmor or Ramsey Outdoor. Also look up NJ Trail Series for trail races in Northern NJ.
You are within 30 minutes of both Ramapo and Harriman, which have hundreds of miles of tough technical trails in them, as well as right next to the Palisades, which has a lot of roads to run on (not sure about trails as I have never run there). By August many of us will be training for Mountain Madness so there will be no shortage of trail runs going on in Ramapo.
