2 hours if it's a get up and go utility ride (not that I moved any faster with a car...)

About 15 minutes for short fun rides. Grab water bottle, bike, helmet and go. I usually don't go more than about 5 miles from home, and I can walk that distance easily as long as I have water. Longer fun rides mean I need to pack a lunch, and sometimes other stuff so the time til I'm out the door goes up.
