The race features all-new, officially measured and certified courses by World Athletics in cooperation with AIMS, with the half marathon route being mostly flat with long undulating hills.

Why attend here

September in Bangkok is still warm and humid, so the early-morning start is a welcome relief. After the race, explore the Grand Palace and Wat Pho, then cool down with a bowl of tom yum goong from a riverside stall.
