The Bangsaen21 Half Marathon 2026 is one of Thailand’s most prestigious races, and this year it will again bring runners to the Bangsaen coast in Chonburi province, less than an hour’s drive from Pattaya. The race will take place on Sunday, December 20, 2026, and its headquarters is traditionally the Bangsaen Heritage Hotel right by the sea. The half marathon distance is 21.1 km along the seafront promenade, with views of the Gulf of Thailand. For those planning an active holiday in the region in December, this is a great reason to combine a beach resort with a world-class running start. 🏃
What is the Bangsaen21 race?
Bangsaen21 is an annual half marathon held in the seaside town of Bangsaen and has earned a reputation as one of the country’s best running events. It is among the road races with the prestigious international World Athletics certification, which means strict course control, precise timing and a strong field of participants — from amateurs to professional runners from many countries.
The atmosphere here is special: the course runs along the sea, the start is traditionally early so runners can race in the cool, and local residents and cheerers gather along the route. Bangsaen is a university and resort town, so the event feels both sporty and warm and homey. Many people come here specifically for this start, combining the race with a weekend on the coast.
When and where it will take place
The Bangsaen21 Half Marathon 2026 will take place on December 20, 2026 in Bangsaen, Chonburi province.

Bangsaen lies on the Gulf of Thailand coast, about an hour’s drive from Pattaya and one and a half to two hours from Bangkok.

What participants can usually expect: a marked course along the coast, food and water stations along the route, electronic chip timing, and a medal and recovery area at the finish.

Practical tips for runners and spectators
The easiest way to get to Bangsaen is by car or taxi from Pattaya or Bangkok — public transport to the start point is limited. If you’re based at the resort, you can plan your trip with our guide to transport in Pattaya.
Housing in Bangsaen and the surrounding area sells out quickly around race day, so book early; the alternative is to stay in Pattaya and travel to the start in the morning, choosing an option from our overview of hotels in Pattaya. Bring comfortable running shoes, a hat, sunscreen and cash — there may not be ATMs near the course. After the finish, don’t rush off: the Bangsaen coast and nearby Pattaya offer plenty of options for relaxation. 🌴
