I have in my past had any where from one to six hour commutes. I don't think it matters as much about the total miles as it does the total time and the stress factor of that time.
I used to drive into Brussels every day, and it was a balls to the wall ride until around one big sweeping corner that you could not see around, a sudden stop, and crawl for the last 40 minutes. For years I'd wake in the middle of the night crying and crying out - "I can't stop!" But I taught myself to slow down a little, and got into listening to audio books. Could really make the time enjoyable.
Driving into DC on I-95 SUCKS!!!!!!!!!!!!!!!!!!!!!!! that was the up to six hour commute. Usually I drive about 32 miles, if I leave on time it is only 40 minutes. If I leave late (several minutes) it is an hour to an hour and a half. If I have to go from home to DC, it is 135 miles and can be as little as 2 1/2 hours, but can be up to 4 - 6 hours.
Over an hour, takes a big toll on you, your body, your mind, your soul, your vehicle, the chores around the house and your ties with your family. Can you do it? Of course. Especially if you can see the end in sight. Would it be better not to? Of course, but we all do what we have to do to get what ever it is we feel we need to get. Good luck in whatever choice you make.
And Chip, there is no way I'd want to ride around 400 miles a day for work. I do like it when we get 400 mile days on our bikes ---------- so I guess as long as the scenerary is worth it, even that could be doable.
