Most of the intermediate level rides I lead for AMC are at the 14-15 av. pace. Sometimes a little less or more. There are weekly Thursday night rides leaving from a variety of places in the western suburbs at this pace. Go to Outdoors.org, click on the Boston chapter, then go to bicycling.

Some of the club rides are very competitive, even at a 15 mph average. Check out different ones, until you find a group that you like.
