Sounds to me like I really need to ride the bike more. Someone (can't remember who) mentioned that I might be over training, which I don't think is the case. I'm working out in the gym on Tues and Thurs with a personal trainer and this week we've really up the cardio aspect of my workout. I also go get on the eliptical for a half hour after my workout with the trainer. Then on wednesday I go back to the gym and do more cardio, with the goal being to work hard. Since I've only *just* upped the cardio aspect, I think that that explains my tiredness. If I stll feel this way next week I'll consider the over training aspect.

I think maybe I need to ride on Wednesday (instead of the eliptical) and Friday as well as the rides I'm doing on the weekends.
