I am up for a cycle ride on the 7th.
Interestingly a number of Cafes are open for ‘take away’ some take cash but others only take plastic, however most do not allow you to use the facilities or sit down at an outside table, e.g. Stansted Park, although you can use the toilets in the Garden Centre if you don’t mind waiting to be let in.
I have no problem with public transport, i.e. train, but you would have to wear a face mask.
