7th Samakkhi Mini Marathon Chiang Rai 2026

The 7th Samakkhi Mini Marathon (สามัคคีมินิมาราธอน ครั้งที่ 7) is a community fundraising event celebrating the 118th anniversary of Samakkhi Witthayakhom School in Chiang Rai. The school's alumni association, parent-teacher association and the school itself are joint organisers, encouraging health, friendship, scholarships and school development.

Race-day timetable and venue

The event is on Sunday 27 December 2026 at Samakkhi Witthayakhom School, central Chiang Rai. The organiser's event announcement gives an 05:00–09:00 Thailand-time overall programme. Crucially, the original organiser's 2026 artwork on its active registration form identifies the opening ceremony and runners' start at 06:00 Thailand time. ARC therefore uses 06:00 (23:00 UTC Saturday) as the start, rather than the overall 05:00 assembly period. Precise distance-by-distance gun times, course access and route maps have not been independently verified.

Exact distance information

The organiser's three actual advertised courses are a 10.5 km mini marathon, 5.5 km fun run and 2 km health walk/run. ARC has no exact 10.5K or 5.5K categories, so they are indexed under the closest 10K and 5K choices only. These are not strictly 10K and 5K races. The organiser advertises Top 118 men and Top 118 women recognition in its 10.5K race; conditions and ranking method should be confirmed directly.

Entries and participant items

General entry is advertised at THB 400, including commemorative T-shirt, finisher medal and breakfast. VIP THB 750 includes a polo shirt as well as the event T-shirt, finisher medal and breakfast. These are entry types that the registration form distinguishes, not separate distance prices. Its official race-shirt chart shows both designs and sizes. Registration and payment are handled through the organiser's TaoDoi registration system; check live availability and current instructions before paying. Race-pack collection arrangements have not been independently verified.

The school map pin marks the general campus, not an independently verified starting arch. Check original event details and the organiser registration form for race-day updates.
