Updated government guidance now says-
"You can leave your home for medical need. If you (or a person in your care) have a specific health condition that requires you to leave the home to maintain your health - including if that involves travel beyond your local area - then you can do so. This could, for example, include where individuals with learning disabilities or autism require specific exercise in an open space two or three times each day - ideally in line with a care plan agreed with a medical professional.
Even in such cases, in order to reduce the spread of infection and protect those exercising, travel outside of the home should be limited, as close to your local area as possible, and you should remain at least 2 metres apart from anyone who is not a member of your household or a carer at all times."
