Most weeks, I work 9 or 10 hours a day, (5 on the weekend days). This is a completely sustainable pace.
When my wife leaves on a business trip, I sprint for 12 to 14 hours per day.
Because I'm forced to take time between sprints, and because I anticipate them coming up and get excited about them, I manage to get into the "programmer flow" on almost every sprint.
I don't believe capping your work week at 40 hours (as recommended in many books) is the right way to maximize productivity because sprinting can be useful and fun. But you can't try to sprint every day, either.
