Riding in twos with people outside your household is legal.
Apologies, yes, I’ve just seen that. What isn’t at all clear is whether or not the 2metre rule still applies. As usual, the guidelines are badly framed and written.
It says “ you can exercise with one other from outside your household “
In the next paragraph it says that you must stay 2 meters from anyone from outside your household.
The new rules? Regulations? Guidelines? are written with all forms of exercise in mind
Otherwise, the only way to get within 2 metres of your mistress, girlfriend, parent etc is to take them on a bike ride.
