Bangkok Marathon 2027 Review: The 37th Edition Starts Beside the Grand Palace

The 37th edition of the Bangkok Marathon is set for 10 January 2027, starting on Sanam Chai Road beside the Grand Palace — one of the most iconic start lines in road racing. Three distances (42K, 21K, 10K) with registration opening nationwide on 1 July 2026. Here's what to expect from Thailand's longest-running capital-city marathon.

Bangkok, Thailand

Last updated August 4, 2026

The bottom line

The Bangkok Marathon — not to be confused with the numerous other Bangkok-branded races — is the city's longest-running marathon, now entering its 37th edition. The start line on Sanam Chai Road, beside the Grand Palace and Wat Pho in the historic Rattanakosin Island, is one of the most photogenic in road racing, and the January date catches Bangkok's cool, dry season. Three distances keep it accessible, and while the course must contend with Bangkok's infamous traffic, the pre-dawn flag-off mitigates much of it. Registration opens on 1 July 2026. Suits runners who want an iconic-start-line Bangkok marathon with decades of history.

The Start Line: Grand Palace and Sanam Chai Road

Few road races anywhere start beside a royal palace. The Bangkok Marathon's flag-off on Sanam Chai Road places runners in the shadow of the Grand Palace, Wat Pho (the Reclining Buddha), and the Sanam Luang royal field — the historic and spiritual heart of the Thai capital. ^[1] It's a start line that justifies the entry fee on its own, especially in the pre-dawn dark with the palace spires illuminated.

37 Editions: Bangkok's Original Marathon

The Bangkok Marathon has been running since the 1980s, predating the city's running boom by decades. ^[1] In a city now crowded with marathon brands — Bangkok Midnight Marathon, Amazing Thailand Marathon Bangkok, and multiple others — the original Bangkok Marathon remains the heritage pick. The 37th edition carries the weight of institutional memory, even if the race-day execution has historically been more functional than slick.

The Date and Distances

10 January is mid-cool-season in Bangkok. Morning temperatures in the low 20s Celsius and low humidity make this one of the more forgiving times to run 42km in the capital. ^[1] Three distances are offered: full marathon (42.195km), half marathon (21.1km), and 10km. Registration opens nationwide on 1 July 2026 via bkkmarathon.com — set a calendar reminder.

Should You Run It?

If you want a Bangkok marathon with an extraordinary start line, 37 editions of history, and cool-season conditions, this is the one. Registration opens 1 July 2026 — don't miss the window. The 37th edition is set for 10 January 2027, starting on Sanam Chai Road beside the Grand Palace. ^[1]
