A few things to note (and maybe it's worth adding a sticky to the top of this board for this kind of info):
If heading via Leeming/NTR, the Costa at Leeming services is now 24hr, the McDonalds likewise. If they are out of commission then the next services (called Exelby Services, but the opposite direction to Exelby from Leeming (i.e. they lie to the North, not the South)) which are ~1mile/2Km away, has a couple of Costa coffee machine, a bike rack (the bus shelter type), a diner, showers and loos. They are also 24hr.
There is a new bypass between the A1 and the Leeming/Morton on Swale road, it's generally quite nice to cycle on (certainly much nicer than the old road used to be) as it is wide, has half decent sight lines and a wide hard shoulder for escape maneuvers.
None of the supermarkets in NTR are 24 hours. The Co-ops (all 5 of them) have cash machines, though (though one, on Romanby Green) is only accessible when the store is open.
