I'm home based but 3 out of the 5 days I'm in one of our offices. I can travel anywhere between 40mins to 2hours to get to one of our offices. On a rare occasion I go up to Glasgow which if I drive will take 4+ hours.
BUT - I don't have to do an 8 hour day when I get there which really makes the difference and can stay over in hotels.
If I was doing 9-5 for 5days a week then an easy travelling 60-75mins would be OK as I'm used to it. Being stuck in traffic for that time would tip me over the edge so it would have to be 60mins at 50+mph
Plus all my fuel is paid so distance isn't a bother.
