My commute is around 30 minutes, via the back roads on my motorcycle. I can shave 5 or so minutes off of that, if I take the car via the M4 - but the motorway isn't as fun!
I used to commute ~1 hour each way for a fair few years, but that was mainly M4, and pending closure/accidents, that time could be double (or more) on the way home - but thankfully that was quite rare. I could just about tolerate that length of commute, as it gave me a chunk of time before/after work to listen to music and relax a bit.
