Bangkok Marathon locks in November 8 comeback

The starting horn cuts through the dark, sharp and unmistakable, and suddenly the city shifts gears. Trainers slap the pavement in quick succession as runners stream through Bangkok's historic core in neon kits, old race tees and race-day shoes worn in just right –  proof that the city barely sleeps in the first place.

Mark your calendar: the Bangkok Marathon 2026 returns on Sunday November 8 for its 37th outing. Every year, it pulls in everyone, from nervous first-timers testing their stamina to seasoned marathoners chasing a personal best, all moving through landmarks that look completely different before sunrise.

Distances range from manageable to slightly unhinged, depending on your mood.

• 5 km – Fun Run
• 10 km – Mini Marathon
• 21.1 km – Half Marathon
• 42.195 km – Full Marathon

The timings lean fully nocturnal, which only adds to the atmosphere.

• 11pm (Saturday November 7): arrival and check-in at Sanamchai Road
• Midnight: full marathon start
• 3am: half marathon start
• 4.30am: mini marathon start
• 5am: fun run start
