Subject:RE: Garmin avg run/bike speeds to HIM race speed
About 1.5-2.5 mph slower during training for many different reasons including...
Poorer road surfaces during training Stop lights/signs, water refills, and riding more cautious on downhills during training Race wheels, tires, tubes, helmet during HIM Taper

Really it depends on your course (both the training and race courses). I can avg anywhere from 16-20 during training and most of my races are in the 17.5-21.5 range.
