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

Why attend here

September in Bangkok brings the tail end of the rainy season, so expect brief showers that cool the air and leave the city's green spaces lush and vibrant. After your run, explore the historic canals and temples of the old city, then refuel with a bowl of spicy, tangy tom yum from a riverside stall.
