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. 

The Preserve Hua Hin Group continues to lead impactful environmental and social initiatives aimed at sustainable practices, inspiring both residents and visitors to adopt practices that protect Hua Hin's ecosystems for future generations.  

The Hua Hin Marathon has always been more than just a race but a celebration of health, nature and the local community. From the 5km fun run to the full 42km marathon, runners enjoy a picturesque route with scenic coastal views and rolling hills set against the soft dawn light as the sun rises over Hua Hin. Beginning and ending at the Buddhist temple Wat Khao Krailart, runners also experience the vibrant spirit of the local community shaping the route. 

The race welcomes runners of all levels with distances of 5 km, 10 km, 21 km and the full 42 km marathon, each route offering its own moment of challenge and exhilaration. To commemorate the event's prestige, the first male and female finishers in the marathon will be honoured with the Royal Trophy graciously bestowed by Princess Maha Chakri Sirindhorn, celebrating not only athletic excellence but the spirit of dedication and perseverance that defines the race.

More than a race, the event reflects a deeper commitment to sustainable wellbeing. The marathon supports environmental initiatives such as the Krailart Niwate Mangrove Preservation and Ecosystem project and community development in Hua Hin while encouraging people to embrace healthier, more active lifestyles.  

Inclusivity is central to the event's ethos, with visually and hearing-impaired runners welcomed to participate alongside volunteer guides under the inspiring theme “Run2gether.”  

Embodying the marathon's ethos of health and sustainability, Chiva-Som invites both local and international runners to enhance their race experience through its exclusive Rest, Run and Recover offer, featuring savings of 15% on retreat rates for all marathon participants.
