I've got a similar problem -- used to live 15 miles from my employer, which would get me to work in slightly over an hour. Current address and employer is 22 - 25 miles apart (depending on route). Solution: cheat a little bit. I've converted to an e-bike (added a hub motor kit). You can set it up so that it gives you assistance, but still requires peddling. Upshot in your case, is you can get a 6-mile workout, while traveling 12 miles (you basically ride in a higher gear, so you go faster/further for a given effort level). I've also seen people get an extended-length cargo bicycle, add the electric assist, and use it to take the kids to where they need to go along with getting a few days worth of groceries.
