So under quarantine rules am I allowed to go for a bike ride? I live in a very rural area

You're fine. It's the cities that are in trouble cause everyone is so close together and women don't wash their fucking hands after using the bathroom.

should be fine, and even beneficial. some sunshine to up your vit D, some exercise to manage stress. just don't run anyone over.

I don't see why not as long as you don't go near anyone ..i walked my dog this morning!

Check your local authority website for detail specific to where you are.

Yes. You just can't get too close to other people

Of course, but no tandem biking.

They won't arrest you, go for a ride.
