You're right ayermail2, lately there has been a strong head wind and I have to really ride hard to keep my average speed at what it used to be. There are a lot of variables to it.

Thanks wawaski, I like your book.

Diane, we did the Texas Coastal Cruise and it was fun. Completed our first century. What an accomplishment. I can't remember what my average was. This Saturday we are going for our second century (Pineywoods Purgatory). My rides have always been on flat land, this one has hills. We'll see how it goes. I'm looking forward to it.
