Denai Ultra Sungkai (DUS) is an event organized by Denai Ultra and will be held on 12th October 2019 at Felda Residence Hot Springs, Sungai Klah, Perak, Malaysia. This year will be the second edition of this fun and action-filled trail event. With a few attractive destinations such as hot springs and nearby pristine river, the route will also traverse through Felda settlement. The start and finish venue will be at the Felda Residence Hot Springs Sg Klah. This can be a suitable run-cation activity.

DUS is separated into three distance categories, 50km, 25km and 10km. This event will consist of Felda's own palm oil open wide trail at Sungai Klah and Trolak and tarmac road along the Felda settlements with elevation gain of 1504m, 356m and 150m (+-) respectively. Surely this will be a fast trail race that will get your heart pumping.

The 25km category catered for beginners to season runners who want to go the distance but not ready for ultra-distance. The 25km is with extended route until Felda Trolak settlement with another river crossing and to return with different route back to Felda Sungai Klah trail/tarmac.

The 50km category is the main category for season runner who want an adventure. Very suitable for first time ultra-runner (with proper training). This year 50km category will be featuring a new route for the second half of the race. Runners will experience a mix of trail and road in Felda Sungai Klah, passing by the Perak Wildlife and National Park, Sungkai and into the jungle trail after the Sungai Klah Orang Asli settlement.
