Hi
Is it "normal" that I feel sore (read VERY sore) after longish bike rides?

The first time I did a 50-mile-ride I was sooooo tired I crashed when I got home and hardly had any energy left to eat. However, I didn't feel sore or pain. Just very tired.

One year later I can do 50+ miles and still have energy left to walk my Westie and do chores. I have learned what & how often to eat and I do switch positions when I ride long distances. But in the last few longish rides I got REALLY sore and had to take tylenol after the rides to alleviate the pain.

Also, I sometimes have trouble falling asleep after a long ride. Why is that? I was tired wanted to sleep but couldn't!!! So frustrating.
