Athletics
Danish athletes have so far achieved qualifying standards in the following athletics events (up to a maximum of 3 athletes in each event at the 'A' Standard, and 1 at the 'B' Standard). Joachim Olsen originally claimed a bronze medal in men's shot put. On 5 December 2012, the International Olympic Committee and the IAAF stripped off Ukrainian shot putter Yuriy Bilonoh's gold medal after drug re-testings of his samples were discovered positive. Following the announcement of Bilonoh's disqualification, Olsen's medal was upgraded to a silver.
