I've been going through that "disconnected" feeling too, lately. I think about riding and get excited, but when I get on the bike and start rolling...my body just doesn't wanna do it. It's not a hunger thing, because I always eat before riding...so it's definitely not that. For me, I do think it's a lack of good sleep. I don't ever get a restful sleep at night, so I always wake up feeling tired, groggy, and cranky. Usually, once we're into the ride for a few miles, I start to wake up and feel better. But occasionally, that tired feeling never goes away...those are the rides that I end up wishing were over sooner. I also don't seem to recover well after long rides. This weekend was a fine example of that. We rode 85 miles on Saturday, 102 on Sunday, and 77 today. Now I have to go to work and I feel totally exhausted...like I could literally fall asleep right now and not wake up til morning. Tomorrow's ride will be short and a very casual pace...that's for sure.
