But when you are taking a rival team back to your former home, relations and loyalty start to get stretched.
That is exactly what husband and wife Andrew and Sandra Winnie will be doing when they return to the Shetlands with Jersey next month.
The couple lived in the Shetland Islands for eight years and were both involved in the development of athletics.
However, after accepting a role as Jersey’s athletics development officer, Andrew and his wife moved to Jersey.
This year Andrew is team coach for the men’s athletics side while Sandra is the team manager for the women’s athletics team.
