Below we look at what this race is, when and where it takes place, what participants can expect and how to prepare for the start.
What this race is
Ruammit Ultra Trail in Chiang Rai is a mountain trail race in northern Thailand. The event falls into the categories ultra run, half marathon, mini marathon and fun run, meaning courses of very different difficulty levels are held on a single date.
According to the registration page, participants are offered the following distances: 50, 35, 12 and 3 kilometers. The longest is an ultra distance with significant elevation gain on mountain trails, while the short 12 and 3 km courses suit family or recreational participation. The route runs through forest and mountain sections around the village of Ban Ruammit, known for its elephants and the Kok River. The organizers publish the exact course profile, time limits and aid stations on the registration page and update them closer to the date, so be sure to check the current map and rules before the start.
When and where it takes place
The essentials on dates: the race takes place November 7–8, 2026. A two-day format usually means the starts for different distances are spread across the days; for the exact schedule, see the registration page.
Start point — Ban Ruammit School in Chiang Rai Province, in northern Thailand. The village of Ban Ruammit stands on the Kok River and is known as a starting point for boat trips and a place where visitors come to see elephants. The nearest large city is Chiang Rai, and you need to reach the start by car from there. November marks the start of the cool dry season in the north, so the weather is usually more comfortable than during the peak of the rains. Public transport probably does not run directly to the start, so plan your logistics in advance.
Traditions and what participants will see
The highlight of the trail is the courses themselves: mountain paths, forest sections and views over the Kok River valley. The race takes place in a scenic area that many travelers know from elephant tours and river rafting trips.
A November start is a big advantage: the rainy season usually ends by this time, the trails dry out, and the air in the north gets cooler. For runners, this means more predictable conditions than in summer. Beyond the sport, the Ban Ruammit area is interesting in its own right: the village and the Kok River are a popular destination for day trips from Chiang Rai. The organizers describe the start infrastructure, aid stations and transfers on the registration page, so it is not worth expecting them to be known down to the minute in advance.
Practical tips for travelers
The easiest way to get there is through Chiang Rai city: first travel to the city, then continue by rented car or transfer to Ban Ruammit. Allow extra time for the trip through mountainous terrain.
Taking part in the race is paid, with online registration — check the exact cost for each distance on the registration page, since the price depends on the course and the application deadlines. Bring trail running shoes with grippy treads and a supply of water; even in the dry season, mountains can be cool in the mornings, so light warm clothing will be useful at the start. Be realistic about your fitness for each distance: the 50 and 35 km races require preparation. It is best to book accommodation in the Chiang Rai area in advance.
