legally you have to stay local;
Please can you point to where that is said in law please?
I was trying to phrase things simply in order to answer a simple question. But if you really want to dive into pedentary,
the law is here...
1.—(1) No person... may leave or be outside of the place where they are living without reasonable excuse.
(2) For the purposes of sub-paragraph (1)—
(a)the circumstances in which a person has a reasonable excuse include where one of the exceptions set out in paragraph 2 applies;
(b)the place where a person is living includes the premises where they live together with any garden, yard, passage, stair, garage, outhouse or other appurtenance of such premises.
(3) This paragraph does not apply to any person who is homeless.
The law acutally stll refers to the old tiers but current legislation has been reworded to apply to all tiers.
There are 20 groups of exceptions quoted in the legislation that qualify as "reasonable excuses" So to be precise - you need to remain at home unless you are out for a permitted exception, and doing so is resonable. The original question was about recreation and not, for example, about being an elite athlete or campaigning in a general eleciton so going into 20 exceptions didn't seem relevant.
For the majority of people the majoirty of the time, to be rasonably following these exceptions you need to stay local. While the guidance is not the law, it can be cited in whether or not what you did was reasonable: like not following the non-obligatory parts of the Highway Code, choosing to ignore the guidance when there is not a good reason to do so could be enough to push an excuse into the realm of the unreasonable.
I can go to the bank, but if I decided to travel from County Durham to Cornwall to use the branch of Nationwide in Truro I might reasonably be said to not actually be out for the purposes of withdrawing money, but for travel. It's permitted to travel for exercise but it would be hard to say that it's reasonable for me to need to do this by hiking up Scafell Pike.
The exemption
to visit a public outdoor place for the purposes of open air recreation
added after 8th March does complicate matters - if your outdoor recreation is rock-clibmbing, it might make it reasonable to travel several hundred miles to get to the nearest large cliff-faces. If your outdoor recreation is surfing and you live in Coventry, maybe you could make a case for going to the coast. But I wouldn't want to be sure about this - is it reasonable to need to do specific forms of outdoor recreation if other forms of recreation are available to you more closely? Either way the question was about afte 29th March when this element will be removed so it seems safer to provide cautious advice rather than risking advising our hypothetical Coventry-based surfer to open themselves up to a fine.
Anyone who is confident in their reasoning to not stay local for an activity is free to try it and take the matter to court if questioned.
