In that case, Steve, only you will know what's right for you given all circumstances.
As far as I can tell, the government website states: "stay within your local area" and local area is defined as your village or part of the city in which you live.
So, strictly speaking, where I go is not my village, although only 2 miles away.
In terms of what is right for me, when these were open/not outlawed I gave up pubs, restaurants, family members' houses, swimming (which has been a daily morning event for me for years) among other things. My thinking behind that was this: firstly, I did not want to pick it up and pass it on to a member of my family; secondly, the thought of picking it up and passing it on to anyone who may die alone and frightened; thirdly, as a country we'll never get out of this unless either saved by a vaccine or everyone does their bit to contain the spread, and it follows in the meantime we'll just go 'round in circles of opening up/ restrictions/further restrictions/opening up and we'll serve merely to delay the date people die and strangle the economy at the same time helping no one in the medium term. We don't have the people to do their bit so we're not getting out of this any time soon.
Long story short: I have been more than willing to give up an awful lot that is important to me, and I'll gladly continue to do so in order to help save lives and move along the path of getting the country going again; but the common denominator behind all of these things is indoors at close quarters with other people. I draw the line at going two miles on my own and not meeting anyone while walking in the fresh air.
