Not really. It's the same route as last year, and goes through Goole and there is a railway station at Scunthorpe where it's possible to wait for the first train.
Howden is another bail out possibility, and it's on the Hull-York line.
About 25 miles in, so there could be a long wait for a train assuming you'd get there before 3am.
If you get as far as the bridge, Brough station (over the bridge and turn left) is a bit closer than Hull station, although having got that far you might as well complete the ride.
Oh I know the hills. South Ferriby is the awkward one. Also I might be riding back which takes in the long hill out of Hull up to the Weedley transmitters.
The left fork about a quarter of the way up the South Ferriby climb leads to a track beside the estuary and then to the bridge.
It's flat or downhill so removes a significant amount of climbing, but the last hundred metres or so is compacted earth singletrack.
Passable, although I pushed for a bit.
Not really a goer for a large group in the dark, or at any time if it's wet.
