We were doing a 100 mile Berwick to Newcastle when I did it. The others managed to ride the fields, I pushed for stretches. OK to a point, but with a hundred miles to do, it got us off to a slow start. I looked at the map later, and there's no obvious road alternative. Apart from a short stretch of the A1, which is single carriageway at that point and always busy, so would be a bit dodgy on a bike.
