Join Ultra Park Run Thailand 100 - IAU 100K Asia & Oceania Championships 2025
Thailand is set to host the IAU 100K Asia & Oceania Championships 2025, a landmark in the ultrarunning calendar. Taking place in November at Bangkok’s Wachirabenjatat Park (Railway Park), this Gold Label event brings elite athletes from across the region to compete on a certified flat-loop course in one of the city’s most iconic green spaces. Alongside it, the 6th Ultra Park Run Thailand 100 will determine national champions in the 100 km and 24-hour categories — serving as Thailand’s official ultramarathon championship and a qualifier for the national team.
This dual event marks a major step in Thailand’s mission to elevate ultrarunning to global standards. Backed by the Athletics Association of Thailand and the IAU, it welcomes both top-tier professionals and rising local athletes under internationally certified conditions. With national pride, elite competition, and a growing sports community, this is a defining moment for the future of ultrarunning in the region.
