I guess I was misread
I don't do bike maintenance in the mornings before I ride. Though I do do a quick once over to make sure everything looks alright.
The night before a ride, I lay out my clothes for the ride, get the bike prepared, tires aired up properly, etc. I don't load it, because I don't want it sitting out in the open all night on a hitch rack. Ours is a safe neighborhood, but still.
In the morning, the alarm goes off at 5:30. I try to get up for it, but I usually get in one snooze button, so I'm up at 5:40. I get dressed, fill the water bottle, and fix myself something to eat so I'm not out there on an empty stomach. Usually a slice of whole wheat bread w/ some peanut butter. By the time I load the bike and get out the door, bread in hand, its usually about 6 AM. I wish I could move faster, but its tough to get going so early. And I have to be quiet so I don't wake the dogs (and thus the wife) up.
The drive to the trail's about 5.5 miles. I park, throw on my helmet and gloves, stretch, grab the bike, do some parking lot laps to get my legs loose, and then set off. Do about four miles, give or take, and then pull back to the parking lot at about 6:45. Load the bike, cool down, and head home. I reach my driveway around 7.
Basically, that hour and a half is all the time I have. I could bike to the trail, sure, but even doing an average 14 MPH it would take me 45 mins. round trip. Assuming I don't get out of the house until 6 AM, that would leave me a mere 15 minutes to hit the trails. And I'd rather spend more time on the trails than the road.
I can't stay out much later than 7, since I have to get ready for work, feed the dogs and myself, and see to it that they get some exercise. Especially in the summer, when my wife gets to sleep in and isn't awake to help out with them.
If it were an option, I'd go in the evening, but I have other commitments then. And besides, the trails get terribly congested in the hours after work.
