My commute is awesome!
I head out the door around 5:15 AM go down to the U of A masters swim practice at 6 AM until 7 AM which is 10 miles. Take a shower and then ride another 10 miles to work. Work then ride another 10 miles home for a total of 30 miles and 1 hour of swimming.
This is a good site on gas prices and why commuting on a bike is the way to go.
