Doi Inthanon by UTMB Route 

The longest of the Doi Inthanon races is the 170km, 100-mile category race the ‘Summit 160’. This is the only one of the races which takes runners to the peak of Doi Inthanon itself, resulting in a total elevation gain of 10045m across the course of the race. 

Like all the others races, the Summit 160 begins and ends at the Doi Inthanon National Park Headquarters. Runners will hit the summit of Doi Inthanon in 51km, with a sharp climb to the top beginning around the 35km mark. A short descent then follows, and by 65km participants will be at the lowest point of the race. 

Across the remaining 100km, runners will contend with several smaller but equally challenging climbs and descents, passing through various sites and villages that litter the National Park before racing to the finish at the familiar Doi Inthanon National Park Headquarters. 

Whilst not taking runners up to the peak of Doi Inthanon, the Cliffs 100 still has a total elevation of 6107m over its 104km. This 100km UTMB category race will take athletes to the cliffs in the national park. 

Again beginning at the Doi Inthanon National Park headquarters, the Cliffs 100 takes runners first to Pha Mon village and will hit its highest point before they reach the Huay Pla Kub viewpoint in 30km. 

Then it’s a long loop back round to the headquarters with more climbs on the way, including a quick ascent after Huai Wok School in the final 20km. 

The Pagoda 50, a 55km race in the UTMB 50km category, takes runners across 3186m of total elevation to the stunning Double Pagoda. The route finishes following the descent down from the Pagodas. 

The 24km, 1067m total elevation Terrace 20 race will take runners along the outskirts of Mae Klang Luang Village and its rice fields. Meanwhile the Tribes 10 race, also a UTMB 20km category event, will have runners climb 712m over its 14km route through local villages.
