We are happy to announce that the Merapoh Rainforest Trail enters the 2026 Grandmaster Quest calendar on the weekend of 1 to 3 May. Under a new event management since the end of covid, Merapoh Rainforest Trail is the successor of TMMT, which was part of ATM from 2016-2019 already. We are indeed delighted our series returns to Merapoh for what has always been a true adventurous ‘jungle’ trail run. 2026 will already be the 5th edition of Merapoh Rainforest Trail, which enjoyed 1600 participants this year.

Merapoh is a small town located in the Lipis district of Pahang, known as "The Caving Paradise." There are approximately 200 caves around Merapoh, rich in historical value and unique features. Additionally, Merapoh serves as one of the gateways to Taman Negara Pahang. Taman Negara Pahang is part of Malaysia's largest national park, covering an area of 2,477 km², and is a renowned eco-tourism destination in the country. The main attractions in Taman Negara Pahang include its geological and biological features, particularly its tropical rainforest that is over 130 million years old.

The event has always had a major community angle. Organising such running events not only promises an increase in local tourism but also benefits the local economy. Persatuan Pencinta Alam Semulajadi Merapoh and MT Tahan Ventures, as the organizers, hope that this event will continue to promote Merapoh as an eco-tourism destination and provide economic benefits to the local community of Merapoh and the Lipis district. This event is fully supported by the Lipis District Council, Pahang State Forestry Department

The event features several distance categories of 10km, 30KM, 55KM, 100KM and 100 Miles. Of these, the 100km and 100 Miles offer a point for runners’ Grandmaster Quest challenge.

Merapoh has several homestay options for runners, which can be checked via the website linked below. Gua Musang is a slightly larger town nearby. International runners can fly into KLIA or also Penang, and take a bus from there.

Registration is already open via checkpointspot Asia - see link below. Note that registrations will close already at the end of March 2026.

Malaysia-based Italian Alessandro Sherpa has a shot at the Asia Trail Master championship lead this weekend as he lines up for the 100km at the Magnificent Merapoh Trail in his residential country. Sherpa needs 400 points (=minimum 4th place) to overtake Pablo Diago Gonzales, but may be keen to make a mark by winning the race ahead of 2017 ATM Champion Steven Ong, who will reportedly be making his first appearance of the season in an ATM ultra race. 

Organised by Ten Senses, mainly known for its road running events in the country, the Magnificent Merapoh Trail - aka TMMT - has quickly developed into one of Malaysia's most popular trail events that attracts a wide international audience as well. The passage through four dark and natural caves is a highlight, as well as the renowned 3km long river crossing. The race courses for all distances (100km, 70km, 35km) have been redesigned for this year. While overall still runable, the 100km now has 2300m of elevation gain as well, or an increase of approx 800hm compared to previous years. Most of this vertical gain will be conquered by the 100k runners just before or around dawn after roughly 50km. The river crossing is now back towards the end of the course, between km 70 and 80, which means nearly everyone will cross at daylight contrary to last year. It has been relatively dry over the past days in Merapoh, so the water level in the river is normal and participants won't have to swim :-). 

Close to 1000 runners will take part, which is the maximum quota for the event given the very remote location on the border between Pahang and Kelantan states, as well as the Taman Negara National Park. 

Among the race favourites we have Alessandro Sherpa, who based on his big victory in Penang Eco 100k last May will find another course very suitable to his characteristics as a trail runner. Japan's Tomohiro MIzukoshi is another excellent runner who could set the pace like he did in Penang 100 miles. Mizukoshi is number 2 in the ATM Championship at the moment, having already completed five ATM races this season. The Tokyo runner will be trying to erase his 8th place (330 points) in Korea 50k in April, his 'worst' result of the season, to boost his ATM championship total a bit higher. He cannot threaten the position of leader Pablo Diago Gonzales, however, as the Spaniard is 240 points ahead and Mizukoshi can maximally gain 170 points if he wins TMMT 100. 

Announced is the return of Steven Soonseng Ong, last year's Asia Trail Master champion, in what would be his first ultra race of the current championship. If he starts, he is always a victory candidate. Sherpa and Ong squared off once before under ATM, which happened in the 100 miles race of Ultra Trail Panoramic in Thailand last December. Ong won. Eight months later, Sherpa has proven to be in great shape while Ong has been very busy setting up his new outdoor and running retail shop in Kuala Lumpur.

There has been speculation that Mohamad Affindi, second in TMMT 100 last year, will also be a late addition to the start list. Affindi has was dealing with the after-effects of the flu earlier this week, though. One dangerous dark horse is Canadian Julian Baker. Based in South Korea, Baker is last year's winner of Ultra Trail Koh Chang 70. This season his ATM record is still blank. 

The women's race was dominated by Tahira Najmunisaa in 2016 and 2017, but now being 7 months pregnant, the female star of Malaysian trail running will be cheering for the others. In fact, remarkably, Tahira will take part alongside her husband Abdul Rahman in the 35km race on Saturday. Malaysia still has a strong runner at the start who could grab the win: Adelinah Lintanga from Sabah. The Grandmaster was 2nd behind Tahira last season. Her main competitors for the podium will be Erin Aziz from Kuala Lumpur and Philippines' Ann Jilian Pulanco - who was 3rd at Dalat Ultra Trail in Vietnam last March. Erin Aziz could be the first woman to reach the plateau of five races this season. After her great 3rd place in Mantra Summits Challenge 75 last month, the ULTRON runner has Indonesia's championship leader Ruth Theresia within sight. Aziz requires 373 points this weekend to claim the points lead, which corresponds to a top five race result in TMMT 100! 

Subject to connectivity, we will be broadcasting and reporting live from Merapoh from start to finish. The 100k flag-off is scheduled for Friday at 9 pm. 

The Merapoh caves are iconic for this event. This year a new technical cave section is added

The organisers of the iconic and important Magnificent Merapoh Trail (TMMT) in Malaysia have released the final version of the course maps and profiles for next week's 4th edition. The race distances have remained at 100km, 70km and 35km - of which the two longest are valid for ATM Championship points - but the elevation gain has increased to over 2000 hm for both 100k and 70k. As a result, the cut-off times may also be increased pending further discussion with the course directors. The late arrival of the new routes is due to significant and also mandatory changes for this year. Cave lovers will be happy to learn there's additional caves in this year's route! The renowned 3km long river crossing is also still in the course. 

For all details, registered participants can download the PDF Guidebook now. 

One of the most anticipated events in the Asia Trail Master Championship, and certainly in the summer months, is the Magnificent Merapoh Trail on the fringes of Taman Negara National Park in Pahang, Malaysia. The 4th edition takes place on 10/11 August and sees some modifications to the route for the two points races distances, 100 km and 70 km. Less ambitious runners can also go for the 30 km. The event gains ever more social importance as well, as logging and road constructions threaten the existence of this ancient rainforest and its inhabitants. By developing ecotourism the organisers of Ten Senses hope to stop this trend and allow the local communities to sustain themselves .

The 100k and 70k feature the passing-through of several cave complexes that characterise this beautiful rainforest area. And this August, runners will enter at least one more cave that is not yet open for tourism. This is a race that looks easier than it is. While mainly flattish, there are technical sections that you are unlikely to forget very quickly. Most legendary besides the caves is of course the 3 km long river crossing, which most 100k and 70k runners will also do before dawn. 

The event has quickly become popular over the past four years and is guaranteed to sell out fast. There is a maximum limit of 1000 runners. So do not hesitate if you want to be part of this great adventure.
