Those are really good points CR400. I'm pretty sure I can do the 112 right now. I just gotta make myself do it. The tough part is that I want to do it several times before I race, and then some. So I know I can get off the bike and run my marathon with a fair amount in the tank. That's where I'm having trouble. I'm not worried about finishing anymore, so I tend to be less disciplined. It's easier to blow off workouts when you're not faced with the threat of not finishing. But at the same time, if I want to PR, I need to put the time in like you said.

But all these responses are going to help me get through the next long ride.
