Thanks for all the responses and encouragement. It sounds like several have been where I am now. After about two weeks of riding I'm starting to enjoy it again and up to 10 miles and around 15.5 mph. That's a far cry from the centries I used to ride at higher averages but it's a start and I intend to stick with it. I need to drop about 30-40 lbs and the only way I was able to do that in the past was with the 50+ mile rides.
As an interesting side note, I have had two flats in two weeks. One was due to decayed rim strips and the other I wasn't paying attention and hit a baseball size rock in the road. I almost went down and now have a new tire on order but until it arrives early next week I am riding on a patched tire. The cords on one sidewall are broken for about 1/4 inch.
