River Kwai International Half Marathon

This is a long-distance running with the longest history in Thailand, founded by foreign runners across the world e.g. Europe, America as results of impressive natural resources and challenging paths. River Kwai International Half Marathon was first launched in 1982, so it could be counted as “The first half marathon in Thailand”. At first, most runners were foreigners whose number combined with that of Thai runners was not more than 100. The event was annually set up continuously and finally has been operated by Amazing Field. River kwai village hotel has always been the event venue and become more popular among Thai and foreign runners. The running event is certified by AIMS or Association of International Marathons and Distance Races that the running paths meet the international standard. In 2023, Redcap Organizer authorized by Amazing Field will solely run the 39th running event.
