This is the season’s main event for everyone who lives for obstacle races. On December 12–13, 2026, the hills and trails of Singha Park will host around 3,000 athletes from more than 30 countries. This is not an ordinary race: this is where the world championship title is contested in the SUPER format. If you’ve long been eyeing muddy courses with ropes, walls, and spears, this is a reason to come to northern Thailand. Spectators have plenty to see too: the atmosphere, national flags, finish arches, and that famous fire jump. 🇹🇭 Current as of June 2026.
What kind of race is this?
Spartan is the world’s largest obstacle race series (known as OCR, or obstacle course racing). The idea is simple and harsh: you run across rough terrain and overcome dozens of obstacles along the way—walls, ropes, overhead structures, carrying heavy loads, spear throws. If you miss an obstacle, you do 30 burpees. The one who finishes is the one who knows how to endure, not just run.
The SUPER World Championship is the series’ top event in the middle distance. Athletes who qualify at stages around the world get in, including at the June Spartan stage in Chiang Mai. For Chiang Rai, this race is special: for the first time in history, the city has been given the right to host the Spartan SUPER World Championship three years in a row, from 2026 to 2028. For Asia, this is a precedent, and for northern Thailand, it’s a serious bid for status as a sports destination.
When and where it will take place
The race weekend of the Spartan World Championship in Chiang Rai 2026 takes place December 12 and 13, 2026, while the expo zone with registration, brands, and gear opens earlier, on December 11. The venue is Singha Park, address: 99 Mae Korn, Amphoe Mueang Chiang Rai 57000.
The location was not chosen at random. Singha Park is a huge green area with tea plantations, hills, and forest trails. Elevation changes and technical stretches turn the course into a real challenge, while also offering that postcard-perfect view of the northern mountains. December here is the cool season, the best time to run: days are warm and dry, without draining heat. We covered the appeal of the north in winter in detail in our guide to the cool season.
