31 October – 1 November 2026 · Wachirabenchathat Park, Bangkok 🇹🇭
Asia's international time-based endurance platform. The distance was conquered — now the clock begins.
Not how fast you finish a distance — but how far you go within the time. Three formats. One platform. Unlimited ambition.
No separate 100K race this year — but 24H runners can target 100K as a personal mission. Hit your goal and stop, or continue to discover how far you can truly go. Official split recognition, benchmark certificate & special digital badge for all 100K achievers.
In November 2025, Bangkok hosted Asia's top ultramarathon nations. Athletes from Japan, India, Australia, Mongolia and beyond competed on this very course. In 2026 — the clock starts again.
The Thai national team will compete at this prestigious continental championship. The Bangkok 24H International team will be on the ground to preview our 2026 platform and connect with the global ultra community.
Ultra Park Run Thailand has hosted world-class ultramarathon events since 2019. Our most recent achievement — the IAU 100K Asia & Oceania Championships 2025 (IAU Gold Label) — confirms Thailand's place on the global endurance map.
Wachirabenchathat Park (Rot Fai Park) — Bangkok's largest inner-city park. A 4KM certified flat loop. Traffic-free. World Athletics certified. And when the golden hour hits the trees, there's nowhere else you'd rather be running.
Full registrations open later in 2026. Register your interest now for early access, event updates and special announcements.
