AIA One Billion Day returned to Khao Yai this year (22 November 2025) with its biggest celebration yet—a vibrant, high-energy festival that brought together more than 10,000 runners, wellness enthusiasts, families, and community partners, all united under one purpose: building healthier, stronger, and more connected lives across Thailand.
This annual gathering is part of AIA’s long-term mission to inspire one billion people in the Asia-Pacific region to live Healthier, Longer, Better Lives by 2030. And in 2025, the momentum is stronger than ever.
A Trail Race That Brings People Together
A key highlight was the AIA One Billion Trail, a team-based running experience designed around the idea that good health isn’t just personal—it’s shared. Teams of four tackled the scenic terrain of Khao Yai, pushing through steep climbs, forest paths, and open fields while leaning on each other for strength and motivation.
More than 700 trail teams and over a thousand individual runners from Thailand and abroad took part, making it one of the largest trail events of the year.
Run, Fun, Share
Beyond the race, AIA One Billion Day transformed AOB Park at The Bonanza, Khao Yai into a lively festival space with a “Run, Fun, Share” theme.
Visitors enjoyed over 30 local food and craft booths—from Korat’s famous monogram cats and Dan Kwian pottery to tie-dye and ceramics inspired by UNESCO-endorsed local heritage. Live performances from artists across generations, including J Jetrin, Som Marie, and Oat Pop Art, lit up the main stage and kept the crowd buzzing into the evening.
Families also joined the adorable AIA Vitality My Melody & Kuromi Celebration Fun Run, marking milestone anniversaries for the beloved Sanrio characters and AIA Vitality Thailand.
Wellness With Purpose
More than just a wellness festival, AIA One Billion Day continues to expand its impact on communities.
This year, the event raised funds for two major education projects:
-
The Thai Red Cross Society’s Language Literacy Project supporting children in Northern Thailand
-
The construction of a Border Patrol Police School in Ban Pa Mak, helping provide quality education for underserved communities
It’s a reminder that small steps—whether running, sharing, or giving—can create lasting change.
Leadership Voices
AIA executives and community leaders joined the event, reinforcing the commitment behind the movement.
They emphasized how collective action, consistent habits, and community support can drive better health outcomes for future generations—aligning with AIA’s vision of a healthier Asia.
Why Khao Yai?
Hosting the event in Nakhon Ratchasima, a UNESCO-recognized destination, also highlighted the importance of connecting health with culture, sustainability, and responsible tourism.
Khao Yai’s natural beauty set the perfect stage for movement, mindfulness, and community celebration.
A Growing Movement
AIA One Billion Day continues to evolve each year, bringing people together for fitness, culture, and meaningful causes. Whether you’re a dedicated runner, a wellness lover, or simply someone looking for a fun weekend outdoors, this event shows how powerful it can be when we choose to live healthier—together.
