It was the fifth edition of the competition limited to British athletes only, launched as an alternative to the AAA Championships, which was open to foreign competitors. However, because the calibre of national competition remained greater at the AAA event, the UK Championships this year were not considered the principal national championship event by some statisticians, such as the National Union of Track Statisticians (NUTS). Many of the athletes below also competed at the 1981 AAA Championships.[1][2]
The main international track and field competition for the United Kingdom that year was the 1981 European Cup. Reflecting the secondary status of the UK event at national level, none of the British individual medallists there were present at UK Championships, though all members of the medal-winning women's 4 × 400 metres relay reached the podium in Antrim (Linda Forsyth, Michelle Scutt, Verona Elder and Joslyn Hoyte-Smith).[3][4]
