With the support of many Japanese running enthusiasts, the Angkor Wat International Half Marathon NGO started the race in 1996, with participants from all over the world. 

The purpose of this event is to raise support for the ban on the manufacture and inhumane use of anti-personnel mines. Entry fees and additional financial support foster independence among landmine victims by helping provide prosthetic limbs, social reintegration programs, and supporting other relevant and needed programs such as education and prevention of any serious new diseases in Cambodia. Another important part of charity also goes to support Poor Children in hospitals such as Angkor Children Hospital and Kantha Bopha Children Hospital.

The venue for this competition is at Angkor Archaeological Park – one of the most important archaeological sites in Southeast Asia. Stretching about 400 square kilometers, it includes forest areas, the famous Angkor Wat temple, the Bayon temple with several other small temples belonging to the Angkor Thom temple complex. Participants can run while admiring the beauty of these UNESCO-listed historic sites.
