I'm in. Assuming trains get me back from London to Nottingham, and I can then cycle to Newark in time to get the train to York I should be there in time for midnight.
If not, it's an impromptu 200km DIY from Nottingham to Whitby, as I've got to meet Sharlotte there as she's got the festival tickets.......
And won't need a bed as should have a hotel to collapse in.
