Whatever you decide to do Crankin, we are cheering for you I can certainly understand wanting to do a century because you want to do a century! I REALLY want to do one this summer myself, but that isn't going to happen. Nothing wrong with being the slowest - but you already know that. I also doubt you would be the slowest Your knowledge of the area is a real advantage should you decide that you need to take a different route back. Whatever you do, have fun!
