9th Kasintorn Mini Marathon Nonthaburi 2026

The 9th Kasintorn Mini Marathon 2026 (กสิณธร มินิมาราธอน ครั้งที่ 9) is a 5 km run/walk organised by Kasintorn Saint Peter School in Nonthaburi, on the north-western side of greater Bangkok. Despite the event's traditional Mini Marathon name, the organiser advertises a 5K course, not a 10K or 21K race. Students, parents, alumni and members of the public are welcome.

Course and race arrangements

• Sunday 13 December 2026: start at Central WestGate Shopping Centre, Bang Yai, and finish at Kasintorn Saint Peter School, Bang Bua Thong, Nonthaburi province. These are different start and finish locations.
• Flag-off time: not confirmed by the organiser information available at the time of listing. Do not treat a venue's opening hours as the start time.
• The school advertises competition for a royal trophy. Specific prize divisions, collection arrangements and running kit contents should be confirmed with the organiser.
• Venue map pins denote the shopping complex and school grounds, respectively; exact start-gate and finish-line positions have not been announced.

Entry arrangements

The organiser's 27 October announcement states that registrations run until 8 December 2026, with a THB 600 early-booking adult promotional rate until 15 November. Standard adult admission is THB 650 for ages 19+, youth entry THB 400 (youth age divisions up to 14 and up to 18), and VIP Family entry THB 600 per person. Verify pricing, remaining places and any conditions with the organiser before paying.

The school advertises in-person registration at its administration office 09:00–16:00, online registration through a QR code on its genuine event poster, and assistance via its official communication channels. No independently verified event-specific direct checkout URL is available, so one has not been invented. Registration and questions should be directed to Kasintorn Saint Peter School. Race-pack collection, individual flag-off and kit entitlements are not yet verified.
