Event Descriptions :

The TMBT is Malaysia's & Southeast Asia’s oldest Ultra-Trail® Marathon. 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 racecourse 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 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.

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 cold, refreshing water for cooling down on a hot day, while 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.
