It is hosted by the Tourism Authority of Thailand (TAT) via its campaign Amazing Thailand with Thailand Tri-League as the organiser. The marathon is categorised as a Road Race label by World Athletics, reaching Bronze label in 2020 for its 2021 race and is recognised by the Association of International Marathons and Distance Races since 2021. The event is officially endorsed by both the central government, and the Bangkok Metropolitan Administration. The event hosts four distances; marathon, half-marathon, 10, and 5 kilometres.
