Italian Giorgio Rubino and Japan's Yusuke Suzuki were the early leaders after 5 km. The two remained half a minute ahead at 10 km, but Rubino fell off the pace and was later disqualified for lifting both feet off the ground. Borchin and Wang Zhen made up ground on Suzuki and after 15 km Borchin progressively pulled away to win the race and defend his title.
In the last 5 km Vladimir Kanaykin and Luis Fernando López finished quickly to came away with the silver and bronze medals, respectively. Wang Zhen held on for fourth, with Stanislav Emelyanov fifth kKim Hyun-sub sixth.[2]
At the time, Borchin became only the third walker to win consecutive 20 km world titles, joining Maurizio Damilano and Jefferson Pérez. Although his winning time was not especially quick, the race was undertaken in hot and humid conditions.[3]
On 20 January 2015, Borchin was suspended for eight years from 15 October 2012, with his results between 14 July 2009 and 15 October 2012 (including his 2009 and 2011 World Championship gold medals) being deleted from the records. On the same day, Kanaykin was suspended for life starting from 17 December 2012, with all of his results between 11 February 2011 to 17 December 2012 (including his 2011 world Championship silver medal) being deleted from the records.
López was therefore declared the 2011 World Champion, with his gold medal being Colombia's first ever medal in the history of the Championships,[2] while Wang Zhen was promoted to silver.
Stanislav Yemelyanov of Russia was originally promoted to the bronze medal, but he was suspended for eight years for a second doping offence from 7 April 2017, with all of his results from 2 June 2009 being deleted from the records (including these championships); this suspension was made indefinite on 2 June 2018.
Accordingly, the IAAF informed the Korea Association of Athletics Federations (KAAF) that Kim would be awarded the bronze medal, South Korea's first ever at these Championships.[4]
