The Beijing International Marathon (Chinese: 北京国际马拉松赛) is an annual marathon race of 42.195 km held in October in Beijing, People's Republic of China. The race was first held in 1981 and has been held every year since. The race begins at Tiananmen Square and finishes at the National Olympic Sports Centre stadium. In addition to the main marathon, there is a 10km run, a mini-marathon and a half marathon. At the 2009 edition of the race, 4897 runners finished the marathon course, which included 556 women.

The race holds an IAAF Gold Label Road Race, one of two marathons in the People's Republic of China to receive the distinction (along with the Xiamen International Marathon). It is AIMS-certified course, making it eligible for world record performances.
The 2012 Beijing Marathon will be held on November 25, 2012.
History
The Beijing International Marathon has been organized by the Chinese Athletics Association annually since 1981. The creation of the race, which was international in nature from its inception, was part of a wider movement to open up China and its culture to foreign innovations – a change which was led by Deng Xiaoping, who sought to move China away from its Maoist past.
In 1986 Taisuke Kodama of Japan set a men's course record in a time of 2:07:35. Ethiopian runner Abebe Mekonnen equaled this time in 1988 and some commentators (including the Association of Road Racing Statisticians) regard this as the true course record, in respect of reports that the 1986 course was around 400 m short of the marathon distance. In 2003, Sun Yingjie of China set the current women's record of 2:19:38 – this run was an Asian record and the fourth fastest ever at the time, and it remains the Chinese record for the event. The 2005 race served as the marathon for the 2005 National Games of the People's Republic of China – Sun Yingjie took the Games gold medal for women while seventh placed Zhang Qingle (18 years old at the time) was the highest placing Chinese man and won the men's Games gold.

Also in 2005, the men's race winner Benson Kipchumba Cherono missed some 800 metres out of the course due to being misdirected. The race organisers accepted the blame for the mishap and, although James Moiben was the first to finish the complete course (2:12:15), Cherono was declared the official winner as he held a large leading margin before the incident.
The competition has hosted the Chinese men's national marathon championships on one occasion (1997) and title went to the race winner Hu Gangjun, who had won in Beijing two times previously.

2012 barring of Japanese runners
When the online registration of runners for the 2012 event started on November 8, 2012, it did so without the option for Japanese to do so. The events organizers said that Japanese couldn't enter this year because of "safety concerns" due to tension between Japan and China over the Senkaku Islands dispute. The Japanese embassy protested the decision.
This move attracted a large amount of criticism and on the night of November 10 the option for Japanese runners re-appeared, although there was no Japanese-language version available, which had been available the previous year.
The Chinese Athletic Association subsequently claimed that Japanese runners had never been rejected. CAA Deputy Director Shen Chunde said that in the past Japanese athletes had mainly applied through Japanese organizations so no individual registration was available.
