BANGSAEN42 Chonburi Marathon 2026

BANGSAEN42 Chonburi Marathon 2026 is a marathon-only race on Thailand's Bang Saen coast, scheduled for Sunday 15 November 2026. The 42.195 km event holds a 2026 World Athletics Elite Label and is also listed by AIMS. The 10th-anniversary edition is designed around a large, competitive marathon field, not a multi-distance festival.

Course and conditions

The race starts and finishes in front of Bangsaen Heritage Hotel. It travels along the beachfront, through the Bang Saen and Ang Sila coastal areas, and past the Chonlamarkwithi bridge section before the Khao Sam Muk climb and seafront return. The late hill and potential coastal humidity are important pacing considerations even though the course has relatively modest overall climbing. Follow the organiser's final 2026 course map and traffic instructions rather than assuming a previous year's road arrangements.

Starts and compulsory cut-offs

The official 2026 starting blocks are 02:30 ICT (elite/semi-elite, Thai fast runners and Block A), 02:45 (Block B) and 03:00 (Block C). The start closes at 03:10 and the finish closes at 10:00, giving the final wave a seven-hour maximum. The intermediate checkpoints are:

• 10 km: 04:45
• 21.1 km: 06:30
• 30 km: 07:56
• 35 km: 08:46
• 40 km: 09:36

Runners over a cut-off may be removed from the course and are not entitled to an official finish, finisher shirt or medal.

2026 entry fees and registration

The published regular marathon entry price was THB 2,000, excluding the THB 50 payment/system charge. Eligible loyalty or lottery entrants could obtain a promotional THB 1,600 rate. The organiser also listed other eligibility-specific programmes, including senior, international semi-elite, late, VIP and charity allocations with different prices and conditions. Registration is now shown as closed/full. The source material does not establish a single reliable timestamp for when every entry route closed, so no precise closing date has been recorded. Runners should only use organiser-authorised channels, not unofficial bib transfers or resale.

Bib collection and race services

Collection is at the Heritage Convention Center, Bangsaen Heritage Hotel on Friday 13 November, 12:00–20:00, and Saturday 14 November, 09:00–18:00 (Thailand time). The organiser requires personal collection; no proxy or race-day pickup is offered. Bring the registration confirmation and identification requested by the organiser.

Available services include official chip timing, pacers, baggage handling, medical points, hydration and nutrition stations, toilets, race photography and post-race refreshments. Race kit and finisher benefits depend on eligibility and successful completion. Check the official BANGSAEN42 website for final race-week operational updates.
