I have this thing, where if I go for a long ride, maybe more than three hours, then boy oh boy I just can't freakin sleep that night. Yesterday afternoon I rode about five hours, and was up at 3 am that night. I can't figure out if it's just due to pain in my quads (they get sore always from riding far), or maybe I'm not drinking enough water or eating enough, and that is causing discomfort that is keeping me awake. Or maybe it's something like I'm still "excited" about going for the long ride that day, even after I get back home and into bed, and there's a high adrenaline level or something that's keeping me awake.
So does anybody else have this problem? What do you think?
