Problem is - I just get so tired after rides and so grumpy that I think my wife is going to take my bike away. For the past few weeks I've been averaging between 4-6hr on the bike with one day devoted to a 40mi ride where I try to keep a pretty high average - which for me is 15-17mph. I'm pretty sure I'm consuming enough carbs/water etc. I usually try to eat the night before good and during the ride will take a few gels - which I realize is probably overkill for 40mi - I just want to be sure my later fatigue isn't carb related. When I've come off the last couple 40mi rides - I'm really depleted. About 20 to 30min after these rides I hit a crazy wall or something and just have to lay down for a little bit.

Yesterday I did the 40mi and was pretty sore. Today I worked out with dumbells in the morning for 45min, light weight. Then after a short nap in the afternoon rode casually to the store and back - about 10mi. Granted it was really hot out - but I drank a whole 24oz bottle of Nuun - average was 13mph. Well for the rest of the day I was a just a tired, cranky ahole. Had to go straight to Starbucks for some iced coffee just to get me through the rest of the day. I just feel I should not be this tired for the expenditure of energy and how focused on nutrition I am.

Other symptoms that probably contribute:
Age late 40s.
Kids wake us up at least once a night.
Lots of family stress.
2cups of coffee in morning - 1cup afternoon.

Might have to give up the bike for a while until I get this figured out which makes me pretty sad.
