I rode 95 miles on saturday(chicago to milwakee) that night i felt good exhausted but good. Usually after a long ride the next day I feel energized, and I was planning on going to Madison on sunday. But i woke up feeling even more tired and slightly feverish. I spent all of sunday in bed. I feel better today, slightly sore but ok. Did i just overdo it? I thought i was in good shape but i didn't ride much this summer, perhaps thats why?
