Just to remind posters that this thread is about the situation in South Wales and to remind some people what the situation is I have just this minute C&P'd this from the Welsh Government site .
Can I exercise by going fishing or horse riding?
This is not specifically prohibited. However, you should not be driving to get to somewhere to exercise, and the need to carry sports equipment isn’t regarded as a justification on its own for driving in these circumstances. This will mean in practice most people cannot do these things while we are in alert level 4.
All exercise must be undertaken alone or with members of your household
That's it .
