About TMBT Ultra Trail 2018

The Race

The Salomon TMBT Ultra-Trail® Marathon 2018 will be held on Saturday, 1st September and Sunday, 2nd September, 2018.

The TMBT is Malaysia's oldest Ultra-Trail® Marathon 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 TMBT course is set over the ridges and in the river valleys around the base of Mt. Kinabalu, with the highest elevation on the race course just under 2000m.

The event takes runners from the quaint native villages at the foothills on the western side of Mount Kinabalu towards the southern side of the mountain with the 30k and 50k categories finishing at the viewpoint to Mt. Kinabalu at the township of Pekan Nabalu. The 100k category continues around the base of Mount Kinabalu and to the South-Eastern ridges of the mountain to finish in the village of Kundasang.

The routes are challenging but beautiful and give runners an opportunity to experience remote villages and follow village trails through a varied landscape of forest and cultivated areas. Trails pass paddy fields and climb steep ridges clad in pineapples with amazing views to Mt. Kinabalu and over the surrounding ridges and valleys which are often shrouded in clouds. The routes cross numerous streams with refreshing water on a hot day, while most larger rivers are crossed via hanging, bamboo or log bridges. Part of the trails follow the old heritage trails that used to be a part of the old buffalo trading routes linking villagers from Kota Belud to Bundu Tuhan.

The race has a reputation for being challenging to complete with a combination of 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. 

Race Categories

The 8th version of the TMBT Ultra-Trail® Marathon will include the original 4 distance categories ranging from 12 km to 100 km that start on Saturday morning plus an additional shorter 7.5 km loop that starts Sunday morning from the finish area for the 100 km at "Perkasa". The 7.5 and 12 km categories are designed to allow newcomers to experience the thrills of trail running. The 30 km and 50 km categories are designed for intermediate trail runners while the full 100 km category is catering for experienced trail runners.

The 2018 routes for the 12, 30, 50 and 100 km are similar to the 2017 courses. The additional 7.5 km course may be entered as a stand-alone race or as an "add-on" race to one of the 12, 30 or 50 km races at a discounted rate (please refer to registrations). The 7.5 km race is intended to give people a chance to experience a small section of the second half of the 100 km course. Although short, it has significant elevation loss and gain, and should not be underestimated. There are no age restrictions for children accompanied by a parent or guardian, and we will have a special category for kids (younger than 14 year) for this distance category. Maps and race course stats are shown under "Route Profile".

The 12 km, 30 km, 50 km and 100 km race courses start at the same location, Kg. Lingkubang in Kota Belud District along the Kadamaian river. The different categories will be staggered in time to reduce trail congestion.

Qualifiers and Championship Points

In addition to being part of the Ultra-Trail World Tour Discovery Race series, the TMBT is a qualifying and point earning event to several races and championships.

Borneo ULtra Trails is a member of the International Trail Running Association (ITRA), and the TMBT courses of 30km and longer are rated under ITRA. This makes the TMBT a qualifying race for all races referring to the ITRA points for qualification such as for instance Ultra-Trail Mt. Fuji. In addition to this, the TMBT is a qualifying event to take part in large international races and also a point earning race in international and national championships as outlined below.
