Kionsom Waterfall, about 30km from Kota Kinabalu or 45-50 minutes drive from the city, is being transformed into one of Kota Kinabalu’s more popular tourist destinations.

Kiulu is located about 60 km from Kota Kinabalu and is the venue for this traditional sporting challenge. The Kiulu 4M Challenge consists of four traditional sports.

The ‘M’ in 4M stands for the four Kadazandusun sports comprising of managkus (running 6 km), mamangkar (bamboo rafting for 5 km), manampatau (swimming with bamboo for 1.3 lm) and mamarampanau (walking with bamboo stilts for 0.2 km). All four are indigenous, adventurous and thrilling events that will test your physical and mental skills.

Besides being a sport event, the K4MC is also a noble endeavor to protect and preserve nature, in particular the  Kiulu River.

Among the objectives of the challenge are to promote traditional sports as an eco-tourism product of Kiulu to create opportunities for active local participation in the tourism industry and instill environmental awareness among the community.

Organizer of the one-day event have also introduced a new category called X-treme 4KMC for men above 21 years old only which involves running and bamboo rafting over a distance of 13 km.
