Borneo Ultra Trail Marathon, better known as BUTM, is celebrating its tenth anniversary this weekend in Kiulu, Sabah, Malaysia. Formerly referred to as the ‘little sister’ of TMBT, BUTM has developed into an early season classic of its own right that plenty of trail runners want to add to their finisher collection. Taking place later than usual this season, BUTM has the typical Sabah ingredients: hot and humid weather during a tough, but fantastic run through hilly rainforests and river valleys with a great vibe of local hospitality and support.

Both the 105km and 55km races are again qualifiers for the Asia Trail Master Championship points ranking. The 105 will also give registered finishers a point for their Grandmaster Quest.

The start list sees the usual stars of the Sabahan trail scene, with in the men’s categories Milton Amat aiming for another win on the 100km and Wilsen Singgin on the 50km. Milton starts as the one-to-beat and it will be interesting to see if anyone else can rise to the occasion this season and get closer to the local star. Other contenders such as Jainuddin Sainuddin, Muhammad Hijazi Rija, Willy Wilson and Bernardo Linus can in any case aim for an attractive podium finish. In the women’s 100km, Adelinah Lintanga could eye another victory under ATM. She may need to watch out for SIngapore-based Filipino Mia Revilla and Hong Kong’s Silver Grandmaster Ellen Cheng.

More than 400 participants on the 50km, so we may get to know some new names, but Wilsen SInggin may also be seen as the big favourite on this distance. His main rival for victory may be Amir Zaki, making his return to the ATM scene after a two-year-break. Ahmad Tanjong and Gustin Tiam can also be in the mix for podium at least. The women’s 50km has one of the top finishers of the recent ATM Championship Final and part of the winning national team: Chisato Kario from Japan. Already a race winner in PMTF and UTSG last season, Chisato Kario is a 50km specialist used to the climatic conditions of Southeast Asia. Her main opponents are likely to be Lolita Lintanga and former BUTM 50 winner Shamiera Auther. It will be interesting to see how they fare against the Japanese runner.

ATM will be reporting live from Kiulu and BUTM on the usual channels, with livestream subject to connectivity.

This weekend we have the 5th edition already of Sierra Madre Trail Ultra, the 75km ATM Championship and Grandmaster Quest qualifier in the Rizal Mountains close to Manila, which has really developed into a new event classic. Organised by the Maharlika Team, SMTU is just good old-fashioned trail running powered by passion and with only 1 race distance on the programme : 75km. Hence, there’s always a good competition between well-known trail aces, who all like to add a win at SMTU on their career records. For others, newbies and short distance runners, SMTU may be the target, the goal for which they trained all year. It’s 75 km and it’s the only finisher t-shirt of the event.

Kristian Joergensen, winner in 2024 and second behind the surprising Randolf Gonzales in 2025, returns for the third year in a row. He is quite at home in the Rizal mountains, of course, and the usual hot weather tends to not affect his performance as much as cold weather. While not in peak form at the 9 Dragons ATM Final five weeks ago, Joergensen remains the one to beat at SMTU. There’s quite a list of other victory contenders, however. Starting with Kik Suello, who beat Joergensen in a dual at Point Trail last year and also finished ahead of him at 9 Dragons. The runner from Zamboanga City has kept on improving year after year and has matured into a proper victory contender whenever he starts a race, which - intelligently - is not that often. Also Jomarc Ferrer has worked himself to the top of the favourites’ lists. Finishing 10th in the ATM Final was no coincidence. This ATM season he has already collected two race wins and he also tops the overall points ranking. Other Filipinos worth keeping an eye on at SMTU are ‘locals’ Maynard Encormal, John Zonio, Anthony Calixterio and Jordan Bugnay - recently third on the podium in V Trail in Laos. But there’s great international talent on the start list, too. Benjamin Nicolas from France, for example, has quite a strong record of performances and is no stranger to racing in Philippines and Asia in general. With Joergensen as a ‘guide’, Nicolas might just as well score his first victory in an ATM qualifier. Japan’s Taichi Yui may also say a few words, though. Already a winner twice this season in the Laos races Luang Prabang and V Trail, Yui showed great running pace but the competitive level will be up a notch this weekend. Also in the field, Hong Kong’s Jeremy Ritcey. On his day still a serious podium contender and not afraid of the heat either.

The women’s race also again has a considerable list of victory contenders including last year’s winner Cecille Wael. When she is in race mode and her stomach doesn’t bother her, Wael might just as well claim the top step of the podium again in what can be called her ‘home race’. But others have shown more competitive consistency in recent months, including Bukidnon’s Shally Yuson and Japan’s Akane Nemoto - both top 10 at the recent ATM Final. Especially Yuson will be very keen to add the prestigious SMTU to her ever growing list of race wins. Akane Nemoto used to live in Vietnam and has won races in Malaysia, so the heat should also not be an issue for the Japanese runner, now back in Tokyo. Former SMTU race winner Ann Jilian Pulanco also features on the start list. For her, it will mostly be a comeback after a prolonged injury break. Another Filipino, but residing in Singapore, who can cause a surprise this weekend is LJ Benitez. She nearly won UTSG 50 last year, and might find the more technical course of SMTU more to her liking.

ATM will report live from Rodriguez and Sierra Madre Trail Ultra as of 1:45 am local time on Saturday.

Last weekend’s Ultra Trail Ha Giang has been won by the pre-race favourites Vang A Tung and Nguyen Ngoc Anh in the male and female category, respectively. Both already scored a second place in VTM last January and are almost guaranteed already of qualification for the ATM Championship Final at Mu Cang Chai Ultra Trail in their home country Vietnam on 3 October.

Vang A Tung completed the scenic, but tough 70km in Ha Giang in. a time of 9h44. That was over half an hour quicker than second-placed Nguyen Hoang Thang. In third place, almost one hour behind Vang A Tung was Truong Anh Dung, narrowly ahead of Duong Cong Bien and former ATM Finalist Do Trung Kien. They all finished ahead of Quang Tran, still on the way back to the front after a few years off the trails. Trung Nguyen did not have the freshest legs after a 100km the week before and finished together with the first female runner in seventh place.

Nguyen Ngoc Anh was almost two hours clear of the next women, showing her dominance in Ha Giang. She came into the finish together with Trung Nguyen , which does show a really strong pace from her part as well! Nguyen Thi Le was second and Ngo Thi Thanh Loan third on the podium.

First ATM race win for Vang A Tung

This weekend the ATM Championship season continues with Ha Giang Ultra Trail in the north of Vietnam, a late sub for the postponed Cuc Phuong Jungle Paths event by the same event management company Race Jungle. On the programme is a 70km race, which automatically is also valid for the Grandmaster Quest. Especially for Vietnamese trail runners, Ha Giang is the last chance to score Championship points within their own country before the Final at Mu Cang Chai in early October.

Ha Giang lies approximately 300km northeast of Hanoi. It’s an area known for its breaktaking landscapes, cultural richness, and the event is recommended by several seasoned trail runners in ATM who have taken part before. In fact, the event offers both trail and road races.

The 70km trail course is quite spicy on paper, though, with an estimated elevation gain of over 5000hm. The race starts at 4am in the morning on Saturday. Expected favourites for victory are Quang Tran, still making his comeback on the trails after a long spell on the road, and rising Vietnamese star Vang A Tung, second in Vietnam Trail Marathon in January. But also Singapore’s Trung Nguyen is on a roll this year, with a race win in Kalaw 100 in Myanmar and a second place in Brah Yang Trail Summit last month. Let’s also pay attention to the performance of Nguyễn Hoàng Thắng, who has been building up a solid competitive reputation as well. The women’s race has Nguyễn Ngọc Anh as potential race winner, also second in VTM this season already. Nguyen Le is also a podium candidate. With 265 runners registered for the 70km, we are certainly bound to discover some new names as well this weekend!

In-form Trung Nguyen already scored a win and a second place in ATM qualifiers this year

This year’s Shiga Kogen 100 near Nagano in Japan has been moved back on the event calendar and will now take place on the last weekend of August. The highly scenic event again features a 100km race as qualifier for the ATM Championship ranking and the Grandmaster Quest. Registration is opening this Sunday evening at 9 pm local time.

Shiga Kogen is one of Japan’s main national parks and also a UNESCO Eco-Park. As the official website reads, Shiga Kogen occupies the center of Joshinetsu Kogen National Park. It is a famous ski resort that hosted the Nagano Olympics (1998) in the winter. During the green season, Shiga Kogen is a treasure trove of nature, with beautiful alpine plants and beautiful lakes and wetlands that can be enjoyed in the vast plateau area. The Shiga Kogen, which has been certified as a UNESCO Eco Park, is an attractive area where nature and human society coexist.

This is a mountainous area so. even in summer temperatures remain cool and are ideal for endurance sports. The start and finish venue is Yamanouchi Town, Shimotakai District, Nagano Prefecture, and lies at about 1600m above sea level, and the highest point of the course is at 2200m. Less ambitious runners can also opt for a 40km category or a 18km category, but these offer no points for ATM.

The 100km has been redesigned for this year’s edition and is said to have become more runable than before. Elevation gain is estimated at 4400 hm. 100km participants are expected to collect their race pack on Friday afternoon, 5 July. The race flag-off is scheduled for 4:30 a.m. on Saturday early morning. The cut-off time is 26 hours, meaning Sunday morning 6:30 am. The podium ceremony will take place after that.

Last year, the male and female races were won by Hisashi Kitamura and Sachi Nakano, respectively.

Registration is open via the official website, where you can also find details on accommodation. International runners are most likely best of flying to Tokyo and take a train or bus to Nagano from there first. Information on event accommodation options can be obtained via shiga100@ktf.or.jp .

One of peninsular Malaysia’s toughest trail races keeps its spot on our Grandmaster Quest calendar this season, but runners should take note of the new event date: Himalaya Sports Tamping Transnaning Ultra has now been scheduled for the weekend of 24-26 July. A race in loops through the heart of Transnaning, featuring seven peaks in 34 km. Grandmaster Quest chasers need to aim for the Ultra race of 68km (4800 hm!) or the Challenger race of 102km (7200hm).

This is an authentic tropical rainforest trail with lots of local history. Start and finish of the event is at the Tampin Water Park in Negeri Sembilan.

The official website describes the route very well: “ Starting from Tampin Water Park, runners begin by taking on the outer segments of the Trans Naning route. This opening section serves as the warm-up, but make no mistake, it is no easy start. Over the first 14km, runners will face more than 600m of elevation gain, with rolling hills on tarmac and forest access roads through the rural foothills. Along the way, runners will pass Kolam Marine A.R.M and the rustic Malaysian kampung landscape before reaching Gunung Datuk Foothill where the real adventure begins. From there, the next 20km reveals the true heart of Trans Naning: a rugged traverse along the southern spine of the Titiwangsa Range, summiting all seven (7) iconic peaks:

1. Gunung Datuk

2. Gunung Rembau

3. Gunung Gagak

4. Puncak 701

5. Puncak 705

6. Gunung Tampin Utara

7. Gunung Tampin Selatan

A checkpoint/water station awaits at the valley between Puncak 701 and Puncak 705 (a.k.a Kem Ultra). The ascent to Puncak 705 is a true test of stamina, as runners drop to the valley floor, reset their elevation, and climb all over again. After passing Gunung Tampin Selatan, runners will then descend and return to Tampin Water Park to complete one (1) unforgettable loop.

Expect dense jungle, narrow ridgelines, steep ascents, and wild, natural terrain throughout the course. With a generous but firm 14-hour cut-off, this category is built for trail runners ready to embrace distance, elevation, and the raw beauty of Malaysia’s mountain heartland.”

Alongside Mantra 68, Transnaning Ultra 68 is valid for the Grandmaster Quest thanks to its elevation gain numbers of more than 4500 hm. It goes without saying that participants therefore need to come prepared for this race.

Registration and more details can be found on the CPS official webpage linked below.

Mexico's Kose Rodarte from Hong Kong's own Gone Running Team won his second ATM Qualifier race in a month at Lantau 70 last weekend.After the 9 Dragons 50km race, he prevailed in the classic race on Lantau island in a finishing time of 7h14'35" . It was a close battle with KC Chan, but the latter had to let go in the final 16km, finishing in 7h26. Good for his first ever ATM race podium, though.

Nepal's Santosh Tamang took third place on the podium in the end. Santosh moved up the leaderboard in the second half of the race, finishing in 7h55. Based in Hong Kong, Santosh Tamang already took fourth place in Ultra Fish N Sheep last October, giving him a solid points total in the rankings for qualification in the Season 11 Championship Final in Vietnam in October. France's Jean Christophe Monnerville was fourth, finishing right behind Tamang. And another minute later, America’s Anthony Lee took fifth place. Numbers six and seven were Daniel Crisp and Arnaud Mauduit, followed by former ATM Champion Alessandro Sherpa. The Italian was running in podium contention for a long time, but the humidity - never his friend - caused him to struggle home. Mark Iandoli finished close behind him in 9th place.

In the women’s race, local Lantau hero Katrina Hamlin won the race for a third time. She caught and passed the fading early race leader Kanako Edamoto from Japan in the final section to the finish at Mui Wo! She crossed the line in 8h04, in the end over 21 minutes ahead of Edamoto, the winner of last year’s 9 Dragons 50/50 stage race. Hamlin, part of Hong Kong’s T8 team, is in the best shape ever.

9 Dragons 50k winner Celine Loubiere arrived in third, giving her real prospects to qualify for this season’s ATM Final in October. Second podium in a month for the HK-based French woman. In four we had Wong Ki Chun, followed by Emma Phipkin and Pak Lai Shan in sixth.

The classic Lantau 70 race in Hong Kong is on again this Saturday. After a heavy HK season, including the ATM Championship Final just a month ago, several of the city’s trail stars are taking a break from Lantau this season, but there’s a long list of competitive trail runners who are very keen to rise to the occasion. Wai Hei Ng might be the one to get most votes if people were to bet on the men’s race winner, but Wai Hei Ng has become a bit enigmatic: will he indeed take the start?

Kose Rodarte won the 50km race at 9 Dragons and could score his second race win under ATM in just a month’s time. What can Alessandro Sherpa do this weekend? So far, Lantau 70 has been a challenging race for him over the years, also due to the often surprising humidity levels. Belgium’s Marc Decamps has been in the top five of this race before, can he climb a bit higher on the ladder now? Others who may have a say in the proceedings at the front can be Dina Bagale and Singapore’s fast road runner Vincent Casanova. The latter may have the fastest legs of all, but how much will the technical sections and the elevation slow him down?

Lantau 70 is also a Grandmaster Quest race, and on the start list is Golden Grandmaster Mario Yap, who has already embarked on the Trail to Immortality. Mario has already even collected 150 points in two countries. Remember, to Become Legend, 500 points and five countries are required. Kenneth Mun Keat Yow so far has 180 points in two countries.

The women’s race at Lantau 70 could potentially develop into a battle between two former 9 Dragons 50/50 winners, Angie Yan (2024) and Kanako Edamoto (2025), and last year’s race winner and local Lantau hero Katrina Hamlin. Even Naomi Fung, winner of the 50k at 9 Dragons a couple of years ago, may have a few words to chip in here. Also Kimmy Leung can claim another top five spot for sure.

The race starts as always at 8:30 am local time.

The 14th edition of Borneo TMBT Ultra Trail Marathon in Sabah is now open for registration. The 2026 edition keeps its end of August slot on the calendar, and once again features 100km and 50km qualifier races for the ATM Championship. Obviously, the 100km is also valid for the Grandmaster Quest.

TMBT is Malaysia's oldest long ultra in Malaysia with the inaugural race held in 2011. The acronym stands for "The Most Beautiful Thing", and makes reference to the iconic Mount Kinabalu, which at 4,100 m is one of Southeast Asia's highest peaks and a world heritage site. The course is considered one of the most beautiful of the season and has plenty of incredible views on Kinabalu and the surrounding areas. A true trail classic, and also the host venue of an incredible Championship Final back in 2024.

While a few changes are expected for this year’s edition, the event takes runners from the native villages at the foothills on the western side of Mount Kinabalu towards the southern side of the mountain with 50k category finishing at the viewpoint to Mt. Kinabalu at the township of Pekan Nabalu. The 109k category continues around the base of Mount Kinabalu and to the South-Eastern ridges of the mountain to finish in the village of Kundasang.

While TMBT may not be the hardest trail race of our series, it is also very often underestimated. The race has a combination of runable bits, steep terrain and technical trail sections, and the weather, usually hot in the first part of the day and with a good chance of tropical showers in the afternoon, often add to the challenge. In other words, come prepared and pay attention to the mandatory gear list for this race.

Last year, Hisashi Kitamura finally got his victory at TMBT, after four consecutive second places. One would think the Japanese “Karate Kit” finally had enough of the race, but in fact he has added it again to his race schedule! Will home hero Milton Amat, or who knows Daved Simpat, take revenge this season?

TMBT is rather easy logistics-wise. Just fly into Kota KInabalu and take a rest at one of the many comfortable yet cheap hotels or guesthouses in the city, before the race shuttle bus at 3 am. All details can be found on the website below.

Hisashi Kitamura finally won TMBT last year, ahead of Milton Amat, in his fifth attempt

Running back in time

Jumla Rara Ultra in the far and remote west of Nepal has been officially announced for 9 May 2026 and will again have a 51km long ATM Championship Qualifier on its event programme. ‘Jumla’ is a high-altitude region where many of the best-known Nepalese trail runners come from, making it pretty much their home race organised by the local Karnali Sports Club. This year will already be the 7th edition of Jumla Rara Ultra.

Certainly, this event is arguably the most remote of all under the ATM umbrella, but those with enough time at their disposal to make the long journey from Kathmandu to the west of the country will be highly rewarded. In fact, runners better arrive several days early to acclimatise as the race takes place at serious altitude from 2300m up to 4017m! The race is from A to B and starts from Jumla bazaar (2305m), and finishes at the Rara lake (2990m). It is a pure mountain trail with hardly and flat sections. The trail undulates and there are three distinct and steep peaks to conquer in the 51km course: Danphe (3500m), Kavra cave, Bhulbhule (2950m), and Chuchemara (4017m). Jumla Rara Ultra Marathon aims to develop adventure sports tourism in Karnali as well as providing national and international athletes a challenging and extraordinary race.

Via the Karnali Sports website, linked below, you can find out all details - including on logistics from Kathmandu.

The 2nd edition of Arakan Mountain Run in Mindanao, Philippines, last weekend counted towards the Grandmaster Quest, but saw some solid competition as well. Ulyses Esteva even managed to win the 80km men’s race by a big margin over none other than Roberto Cain III. In the women’s 80km race, Guia Cabigas once again raised her competitive profile with another victory in Mindanao.

Arakan is a municipality between Davao del Sur and Bukidnon and blessed with natural resources and magnificent landscapes. Organised by Vertical To Sky, Arakan Mountain Run is aiming to become one of the classic events in Mindanao, alongside Mount Apo Sky Race and The Punisher, established by the same company and its director Doi Calbes over a decade ago and still going.

Offering a good mixture of technical and runable terrain, Arakan has something for everyone. Ulyses Esteva was the surprise winner of the men’s long distance ultra, completing the course in 11h04’. Impressively, that was almost one hour ahead of Roberto Cain III and Ronie Jandog. Whilst not taking anything away from Esteva’s performance, Cain III does seem to find himself in a competitive slump - finishing below expectations in the Season 10 Final at 9 Dragons three weeks ago, too.

Guia Cabigas also won her race with a big margin in 19h43. As Shally Yuson, Cabigas is gradually becoming a repeat race winner in Mindanao and someone who keeps improving pace-wise. She was flanked on the podium by Devere Galo and Realyn Lugo last Sunday.

Arakan Mountain Run is on the shortlist to also become a Championship Qualifier in Philiipines in Season 12.

We are pleased to announce that Vietnam Jungle Marathon returns to the Asia Trail Master calendar this year, in particular the Grandmaster Quest calendar! One of the more popular events in the pre-covid era - when VJM was held in May - still offers a highly scenic 70km race in and around the Pu Luong Nature Reserve, around 160km southwest of Hanoi. VJM 2026 is scheduled for the weekend of 17/18 October.

VJM is part of the Vietnam Trail Series organised by the Topas Group, which also includes VTM and VMM. For many trail runners, all three are bucket-list races given their great organisational quality, scenery and vibe amongst the participants. We are indeed happy that people aiming to complete the Grandmaster Quest can now again score a point at VJM. Obviously, the 70km is the target distance for this.

As the website reads, “Pu Luong is an area where time stands still. Pu Luong is home to ancient jungle, soaring limestone peaks, waterfalls, rivers, vibrant rice paddy fields and small villages where life goes on as it has for generations.” The Nature Reserve is filled with rice terrace scenery and you will pass by several small minority villages during a varied race, featuring both runable and technical sections. Estimated total elevation is 3100 hm for the main category, the. 70km.

All details on the course can be found on the official website linked below. Via the website you can also register for the 70km race. Pay attention to the accommodation options and the travel packages on offer from Hanoi including the usual bus transportation from the West Lake on Friday morning.
