is the title sponsor of the marathon. The organizers of the marathon are the National Jogging Association of Thailand and local event management company Amazing Field. The race is also recognized by the Association of International Marathons and Distance Races.

Participants and events

More than 33,000 runners participated in the 2015 edition. Along with full and half marathons, 10 km and 5 km races were also held.

Course

The course passes many historical landmarks of cultural and ethnic importance. The marathon starts and finishes in front of The Royal Grand Palace at Sanam Chai Road. The race course is sanctioned by The Association of International Marathons and Distance Races and the Amateur Athletic Association of Thailand.
In 2013, the course of the half marathon was changed at the last minute because of concurrent Bangkok street protests which reduced the distance of the half marathon from 21.1 km to 19.7 km. In 2015, the half marathon was accidentally extended from 21.1 km to 27.6 km. According to organisers, the increase was due to the race officials directing runners to take a turn at the wrong place which added over 3 km extra to each of the two laps. The mistake sparked humour and outcry in the social and news media. The Guardian called it "world's longest half marathon". Some comments on social media called it a "Super Half Marathon", while some called it a byproduct of "race inflation". Organizers apologized for the mistake and decided to offer a T-shirt saying "Finisher of 27.6 km" to participants who completed the "half marathon". In addition to the half-marathon error, runners in the 10 km race reported that their GPS watches measured that race's length as approximately 9.7 km.
