I have a 5 mile commute and start work at 7:30am. I get out of bed at 6am, shower, pack my bike, eat some toast w/ peanut butter, drink a couple of glasses of water and head out the door around 6:30am. I'm in my office by 7am for cool down, stretching and getting dressed.
When I have to drive, I get out of bed at 6:30 am so it isn't much of a difference.
