I ride during the week, sometimes in the evening with friends after work. I've always done this and enjoyed it immensely once Summer arrives but lately when I've been riding, usually on the later rides starting about 6PM, I get home kinda late and I'm tired from the ride but feeling fine. I eat a little, hang out and wind down and then go to bed. However I can't seem to get to sleep and when I do I wake up a lot. I don't know what's up with this, it doesn't seem to happen when I ride earlier in the day or on weekends, just these late evening rides. It's annoying to say the least but I don't know what to do except deal with it, I don't want to give up my evening summer rides. I've noticed sometimes and not all the time, that when I get very tired physically I can't rest or get to sleep, my mind seems to be still amped up though my body is tired, so it's a mix of mental and physical. I wonder if anyone else suffers from this, I know it can happen to Craig once in awhile too. Sleep is so important to me but as I've gotten older I've noticed it's not always as reliable as it used to be, just something that you have to deal with I suppose.
