Jelebu Ultra Eco Challenge 2026

Jelebu Ultra Eco Challenge 2026 (JULTRA) is a new trail-running festival held in Taman Negeri Kenaboi, Jelebu, Negeri Sembilan, on 17–18 October 2026. The Jelebu district and forestry authorities collaborate with N’Smilan Athletic Club to showcase the area's rainforest, mountains and waterfalls through an endurance-running event.

The organiser advertises three categories: a 50KM Ultra Trail, a 20KM Trail and a 7.5KM Fun Trail. Approximately 90% of the course terrain is trail and 10% is tarmac. The longest route passes Bukit Dapur Moyang, Gunung Besar Hantu, Lata Dinding and Lata Kijang. Gunung Besar Hantu reaches approximately 1,462 metres. The shorter courses feature waterfall scenery around Lata Dinding and Lata Kijang. The 50KM organiser route trace measures approximately 50.8km with around 3,500m of ascent, indicating a challenging mountain race rather than a flat ultra.

The event weekend begins on Saturday evening, 17 October. The 50KM starts at midnight on 18 October, followed by the 20KM at 6:15am and the 7.5KM at 8:00am. The organiser has released current-edition GPX tracks and checkpoint information. The 50KM has seven listed checkpoints, the 20KM three and the 7.5KM one. Participants should consult the latest organiser maps and mandatory-equipment notices before travelling.

The organiser's latest race-pack notice confirms collection on Saturday 17 October from 10:00am to 4:30pm at Taman Negeri Kenaboi. Earlier information also mentioned a Friday collection period, which participants should reconfirm. The organiser has communicated designated parking and shuttle arrangements because vehicle access to the race village is restricted. Drop-bag counters have separate hours for the 50KM and 20KM.

Registration periods and prices were announced for May to September 2026, so new entries should not be assumed available. Official event shirts and special 50KM and 20KM finisher shirts have been announced.
