Absolutely, doing it in half that time would be madness though!

Doing it in half the time would be impossible. To travel 250 miles in three hours you'd need to keep up an average of 83mph-ish for the whole journey.

I shouldn't think there are many places you can reach a peak speed of 83mph for long on the whole road.
