Ayutthaya Marathon 2026: Run The Heritage - Thailand

Ayutthaya Marathon 2026: Run The Heritage brings four road-running distances to Thailand's former royal capital on Sunday 22 November 2026. The event takes place in the historic Ayutthaya area, famous for its temple ruins and UNESCO-listed heritage. The start and registration-area venue specified by the current edition's organiser-linked registration provider is the Old Provincial Hall (former city hall), next to the Ayutthaya City Pillar Shrine. This is a different event from the Ayothaya Mini Marathon on 15 November and the Garmin Run Ayutthaya race on 6 December.

Distances and race programme

• 42.195 km full marathon: THB 1,220 regular entry, starting at 03:00 Thailand time (ICT) in the official programme.
• 21.1 km half marathon: THB 920 regular entry.
• 10.5 km mini marathon: THB 720 regular entry. Note the official distance is 10.5 km, not 10 km. This category is described here rather than being incorrectly tagged as a standard 10K in ARC's distance filter.
• 5 km fun run: THB 520 regular entry.

A THB 3,000 charity entry is separately advertised with choice of distance. The organiser's registration provider offers course diagrams for every distance, so participants should study the 2026 maps rather than relying on general descriptions of the heritage-park roads. The official programme gives 04:30 ICT for the half marathon, 05:30 for the 10.5 km mini marathon and 05:45 for the 5 km fun run. The runner area opens at 01:30; the marathon finish cut-off is 10:00, with the event closing at 10:30. Follow any subsequent official changes.

Registration CLOSED — confirmed by official provider on 3 November 2026

Registration is CLOSED. The official ThaiMaster registration calendar labels Ayutthaya Marathon 2026 “Closed !!”, and its main event directory explicitly says registration is closed. The advertised last day was 31 October 2026 at 23:59 Thailand time (UTC+7), or earlier if the 4,000-place field filled. Historical fees on the event page are not tickets currently available. Any generic “Register” button on an older event-details view must not be interpreted as an active checkout. No authorised extension or reopening was verified; runners should check the organiser's official Facebook page for any change.

The separate 15 October notice concerned the last day to select postal race-pack delivery, not the overall entry deadline. ARC retains the verified registration closing timestamp of 31 October 2026 at 23:59 ICT; no further closing date has been invented.

Runner arrangements

The organiser says all finishers receive a commemorative medal, and finishers of the marathon and half marathon additionally receive a finisher shirt. Event shirts and race maps appear on the official entry page. An advance race-pack mailing option was offered, with an advertised first-runner charge of THB 60 and THB 20 per additional person under the same registration code, with delivery planned for early November. That option was subject to the earlier 15 October cut-off. In-person race-kit collection and expo: Saturday 21 November, 10:00–18:30 ICT, at the Old Provincial Hall beside the City Pillar Shrine, according to the official programme.

Trophies are advertised for male and female overall winners and age-division placings in the longer races, and for leading 5K finishers. Arrive with suitable time for parking and bib checks, and review the final event notices for any course changes, cut-offs, or road closures. The registration provider indicates a total field limit of 4,000 runners.
