how slow am I?

I think one can only comment about another's speed in only 2 cases: 1) a race in which they have the results of the racer's peers for comparison, and 2) if s/he knows firsthand the person's age, weight, bike type, general fitness, bike skills, terrain, distance, solo or pack, pavement quality, temperative, humidity, wind, heath issues and probably a multitide of other things - including the goal of that day's ride.

Look around you at your fellow riders (not forum members unless they also ride with you) if you wish to make a comparison. Then, go ride your ride.

Editing because I keep thinking of things that affect speed.

Also, be sure you compare door to door average speed, not "cruising speed"
