What your average speed will depend greatly on your terrain, your bike, and your condition. For example, as a borderline uberclyde(290 lbs), I will only average about 10-12 mph through the hills of CT doing a century on my road bike. However, put me down in Savannah, GA, and I'll average 18+ mph. If you are only averaging 16 mph now, averaging 25mph for a 100 mile ride will be a pretty tall order to accomplish this season.
