30 miles each way, 5 days a week is a loooong way. It will also add quite a bit to your commute time - last year before moving jobs, I was doing the 60 mile round trip to work once a week - but it did mean I was out of the house from 6.30 am - 90 minutes to cycle in, then get showered, and not home till, 7.30pm...it's a long day...
Try it, but don't expect to do a full week - day on, day off - see how you feel. Go for the country route, it's far more pleasant.
I used to commute 40 mile round trips each day, and with racing at weekends, I'd usually only do 4 days, then have the friday off.
My commute now is a nice 8 miles, but I do it in all weathers. Lots of opportunity to extend it if needed.
Good luck, and don't kill yourself at first.
