There's one thing that fully wakes me up every morning better than a dozen cups of coffee ever would: biking to work.
I'm curious about the logistics behind this. Do you have an issues carrying items to work? Spare clothes, laptop, lunch, etc. Also, do you shower and change once you get to work?
Sweat. If you have a shower at work then great. If not there's no reason to go full tilt on the way to work. Relax, go at a reasonable pace to avoid working up a major sweat. We have a shower at the office, but I rarely use it because it's not too hectic of a ride.
Store stuff at work. Drive into work on a Monday and bring clothes and stuff with you and store in a locker or somewhere at work. Then bike the rest of the days and drive home later in the week.
If you can leave your laptop at work the odd day.. you'll enjoy life at home that much more :)
