It's easy when you make the necessary lifestyle changes and commitment.
When I was doing 70-80 a week while working, I just made running part of work. I knew I would not feel like going out for a run after coming home from a long day of work, so I ran immediately after work every day. On my off days I would run first thing in the morning (usually would wake up a little bit first but no more than an hour loafing around).
Some days the work night went late, like 1:30 in the morning. So I just did my run right after work like any other day. When you attach the running to work, it just becomes part of the work day.
Home was for relaxing.
As far as structure, I was running an hour a day in the afternoon, which I logged as 8 miles (was running between 7-7:30 pace). Hard days were faster than that so I shorted myself a few miles in the log. One day would be a 2 hour run, probably 16. Then I would run 2-3 days in the morning for 30 minutes.
The only time I ran at home was in the morning. I lived on the beachfront and it was very pleasant at 6am. On my off days I would sleep in and run later, like 10am, but I started to get annoyed because people would not leave a clear path to pass them, so I started driving to the base I worked at and running there instead.
If your workplace is somewhere where it sucks to run, just find the best place nearby. Don't go home until your run is done.
Everything else in life comes after the run gets done. This made it difficult if we had a company dinner or something, so on very infrequent occasions I was doing a 10pm run on the beachfront after dinner and a couple of beers (not fun).
