Ronald William Clarke, AO, MBE (21 February 1937 – 17 June 2015) was an Australian athlete, writer, and the Mayor of the Gold Coast from 2004 to 2012.

At the 1968 Summer Olympics in Mexico City, Clarke collapsed and nearly died from altitude sickness sustained during the gruelling 10,000 m race final.

Despite training in the Alps to get acclimatised to high altitudes at Mexico City, this could not put him on par with many opponents from Africa, who had always run at high altitude (with the notable exception of 5,000 m gold medalist and 10,000 m bronze medalist Mohammed Gammoudi of Tunisia, who was born and lived not far above sea level).

On 10 July, at London's White City Stadium, he became the first man to run 3 miles in under 13 minutes, lowering the world record to 12:52.4.

[29] In the 2013 Queen's Birthday Honours List, he was appointed an Officer of the Order of Australia (AO) "for distinguished service to the community through a range of leadership roles with local government and philanthropic organisations, and to the promotion of athletics.

On 15 March 2006, Ron Clarke was one of the final four runners who carried the Queen's Baton around the MCG stadium during the 2006 Commonwealth Games Opening Ceremony in Melbourne, Victoria, Australia.

In 1966 (often erroneously noted as 1968), he invited the Australian to Czechoslovakia, and as a parting gift he gave him his 1952 Olympic 10,000-metre gold medal with the following words: "Not out of friendship but because you deserve it.
