IMO, 10 miles one way is the perfect distance for a vigorous commute. And those who argue that a short commute cannot be much of a work out are wrong. I routinely burn 700-800 calories on my short 5 mile one way commute.
That is impossible. When I was race fit, weighing over 190lbs, I could only just manage to burn 1000 calories in an hour - and an hour, for me, was well over 20 miles at close to 300 watts. To burn 700 calories in five miles you'd have to be putting out something like 1000 watts. Nobody can do that.
