Where'm I At?

I need something to judge my fitness level right now. Running is feeling pretty good. Swimming is coming along and I have a lot of time until I have to put it to race use. I am also in the pool WAY earlier than last year and feeling faster and stronger. The bike is a HUGE question mark. I have no idea how to judge my bike fitness right now. I am ahead of last season for sure, but I have no idea how the time on the trainer is going to translate to road action. I have goals here! I need some kind of guidance.
