Silabur Cave Trail in Sarawak, Malaysia, has been confirmed as a points race for the ATM Championship ranking and Grandmaster Quest also in 2025. The event, organised by Alpha Sports, will see some modifications, including the date. The event will move forward on the calendar by a few weeks and will be held on the weekend of 12/13 April. Also the start and finish site has moved a bit to allow for better mobile connectivity. It will be at Kampung Lubang Batu, Tebakang, which is roughly 40km from Serian town & 100km from Kuching. As usual, there is a bus shuttle service from Kuching for registered runners. Important also: ATM points seekers need to focus on the 100 km.

Silabur is quite a runable 100km , but if wet can be treacherously slippery in parts. Highlight is of course the Silabur Cave, a.k.a. the Jade Cave. Sabahan runners Gustin Tiam and Rejlen James were the fastest 100k runners here in 2024, in a race with considerable participation numbers for a long ultra. It’s mostly a Saturday day time race with the start set at 7 am in the morning. Cut-off time at the finish is a very accommodating 33 hours. As always, but especially in regions like Borneo, take a good look at the mandatory gear requirements and ensure you are prepared for hot tropical weather.

It’s only been a couple of years that Sarawak is claiming its stake on the Malaysian trail running map. Contrary to its northern neighbours Sabah and even Brunei, events and runners were few and far between. Sally Yap, ‘Alpha’ Siet Fah Lim, Celeste Teo and others have changed that, encouraging event promoters and organisers to build proper trail events, too. Alpha Sports is among those with several events in its portfolio. Silabur Ultra Trail, a.k.a. as Silabur Cave Trail is currently the biggest.

Registration for the event is open via Checkpointspot. The official hotel is in Serian, the Roxy Hotel. Runners could also opt to stay in Kuching, main city in Sarawak and where the airport is, and take the event shuttle bus early in the morning on Saturday.
