Set along the tranquil Gulf of Thailand coastline, the Hua Hin Marathon 2026 is set to return on 10 May, offering runners the opportunity to combine athletic ambition with environmental purpose. Organised by the Preserve Hua Hin Group, which is led by globally acclaimed wellness destination Chiva-Som, the marathon attracts local and international runners who seek not only the exhilaration of the race but also the chance to support local conservation efforts, including the preservation of Krailart Niwate, Hua Hin’s last remaining urban mangrove.
