Nan Mountain Trail returns to Na Noi district on 10 and 11 October 2026 with five distances: 9km, 20km, 30km, 60km and 100km. The start and finish are at Prakitwetchasak School, creating a shared race base for first-time trail runners and experienced ultra athletes.
The event’s northern landscape is the attraction, but distance alone does not describe the challenge. Heat, humidity, climbing, uneven ground, stream crossings and darkness can all slow a mountain race. Plan around time on feet and conditions, not a road-running pace.
Choose the right distance
The 9km course is the most approachable introduction, though it still requires suitable shoes and attention on rough ground. The 20km and 30km races demand a more deliberate training block. They are long enough for hydration and pacing mistakes to become significant.
The 60km and 100km routes are ultra-distance commitments. Enter only with recent long-trail experience, tested nutrition and the ability to manage hours of climbing. Review cut-off times and mandatory equipment in the latest runner briefing rather than relying on an older edition’s rules.
Prepare for the terrain
Train on hills and technical surfaces where possible. Long stair sessions can build climbing strength when you live in a flat city, but they do not fully reproduce loose dirt, wet roots or steep descents. Include downhill practice so your legs can absorb repeated braking.
October conditions can change quickly. Shoes should drain well and grip wet ground. Test socks, gaiters, pack and rain layer before travelling. A new piece of kit introduced on race morning can create blisters or chafing within the first hour.
Plan for darkness
Long-course runners may spend substantial time under a dark sky. Carry the headlamp and backup power specified by the organiser, and practise changing batteries with tired hands. A waist light or backup torch may improve depth perception on uneven descents.
Night movement should be slower and more deliberate. Eat and drink on schedule, watch course markers and stop briefly if fatigue makes navigation uncertain. The mountain atmosphere can be beautiful, but a starry view is not a substitute for following the marked route.
Collect your race pack
Race-pack collection is scheduled across 9 and 10 October. Check the time assigned to your distance and bring the required identification or confirmation. Do not leave collection until the final minutes, especially if you need to resolve a missing document or equipment question.
The organiser states that entries cannot be refunded or transferred. All runners receive the official race items listed for their category. The NMT100 package includes a duffle, and eligible finishers receive a hooded item. Treat merchandise as secondary to fit, safety and course readiness.
Allow for park fees
The race fee does not include the national park entrance charge. Published rates are THB 20 for Thai adults and THB 10 for Thai children, with THB 100 for foreign adults and THB 50 for foreign children. Carry a suitable payment method and allow time at the checkpoint.
Fees and access arrangements can change, so follow the organiser’s final announcement. Respect protected areas by carrying out gels, wrappers and tissues. Trail events depend on cooperation with local communities and land managers, and litter can threaten future access.
Reach Na Noi rested
Na Noi is in Nan province, away from the conveniences of central Bangkok. Build extra time into road transfers and avoid a late arrival before an early start. Accommodation near the race base may be limited, so confirm the exact distance and transport plan rather than judging from a province-level map.
Eat familiar food, hydrate gradually and organise kit before sleeping. Pin your bib, charge devices and lay out clothing in sequence. Ultra runners should label drop bags exactly as instructed and avoid packing items they have never used in training.
Race with restraint
Start easier than feels necessary. Walk steep climbs early, keep effort controlled and eat before hunger becomes urgent. In the longer races, a sustainable first half is more valuable than a fast opening photograph. Help another runner or alert officials if you encounter a safety problem.
Recover after the finish
Keep moving gently after crossing the line, change out of wet clothing and begin replacing fluid and food without forcing large amounts at once. Inspect feet before a long drive. Blisters, swelling and minor cuts are easier to manage while medical support and clean facilities are nearby.
Ultra runners should be cautious about driving immediately after prolonged exertion or a night without sleep. Arrange a rested driver or an additional night in Nan. Seek medical help for confusion, chest pain, persistent vomiting, severe weakness or symptoms that do not improve with rest.
