just stick a good lunch break in the middle (will need fuel too anyway) and all will be well no doubt....
I've already got the route sorted....they'll be a stop (point B) for lunch and fuel at 130 miles from Norwich and a slight detour (adds 8 minutes) towards the end just after Darlington so instead of going A1(M) all the way we cut across the A68 at the later part, also I am assuming we can get fuel along the A68 somewhere for the final bit:

We can worry about meeting point for all jumping aboard the EAR express later
