We are happy to announce that BTR Ultra in Bali is making a comeback to the Asia Trail Master Championship calendar on 10/11 May 2025. Organised by the Bali Trail Running community, the event offers breathtaking 100km and 60km points races with the longest race category including the ascent of Bali’s greatest mountain Gunung Agung. Start and finish is in Kintamani by the Batur lake.

Back in 2022, just after covid, BTR was one of the shortest races in our ATM history with a 30km that produced great sparks with Mohamed Affindi and Vanja Cnops taking top honours - short distance specialists as they have always been. You can rewatch the race summary below or on our youtube page. Since then, the event has continued to grow and develop longer trail courses. The advertised 100km is special as it includes the three big Bali mountains with Agung, Batur and Abang. Total elevation gain is quite serious, approx 7250 hm, and runners should also take the heat and humidity into account. Definitely, if one wants to finish the 100k, one should come focused and prepared. The cut-off time of 34 hours, for 106km by the way, is on the tight side. Please also note that the start is scheduled for Friday afternoon at 4 pm. The idea is that the majority of participants can enjoy sunrise on Agung.

The 60km also has no fewer than 3800 metres of elevation gain, but skips Agung. Runners need to conquer both Batur and Abang, and the latter should not be underestimated. Both for the 60k as the 100k races it is worth noting that the final 15km are quite runable so you better leave something in the tank. Apart from the volcano and mountain climbs, runners can also look forward to passages through the black lava field, pine forest and Trunyan Hill.

Kintamani and the Batur lake are located towards the north of Bali. International runners can make their way up from the Canggu, Seminyak and Nusa Dua areas via Grab or motorbike. It may be worthwhile to consider staying in popular tourist place Ubud before and after the race, to cut traveling time to the race venue.
