About this event
AIMS lists Bangsaen21's next confirmed edition for Sunday 20 December 2026, organised by MICE and Communication as part of the Bangsaen race series. The 21.1 km course runs along the Bang Saen beachfront and the Khao Sam Muk headland in Chonburi province, and the race was the cover story of AIMS Distance Running magazine in 2026, a sign of its standing on the Asian calendar. It clashes with the Bangkok Midnight Marathon on the same date, and the Bang Saen start is an early morning one, so most runners stay on the coast the night before.
