Well, this is a biased sample. Riding easily in the morning shouldn't make you sweat. Take the long way home and ride hard.
I have an 8 mile commute, though I frequently take the bus and chop out all but 1.2 miles. Ah, but half of that 1.2 miles is a twisty turny down hill through a park. Hoo Ha! More frequently, I will ride the entire route home.
