A maximum of 2 people from 2 separate households can meet outdoors for sport or exercise. Children under the age of 12 from these households do not count towards this number.
The members of an individual household or extended household can meet outdoors for sport or exercise.
You can travel for local outdoor sport or exercise such as meeting another person, walking, cycling, golf or running that starts and finishes at the same place (which can be up to 5 miles from the boundary of your local authority area), as long as you abide by the rules on meeting other households.
So you can still go and do the Winter Challenges!
