Earn Grandmaster points at Prenn Trail Summit in Dalat

One of the events that is becoming every more popular on our ATM calendar is Prenn Trail Summit in Dalat, Vietnam. Scheduled from 9 to 13 December 2026, trail runners on the Grandmaster Quest will again have no fewer than four categories to choose from in order to collect a new GM point. The longest race category is the 250km mega ultra, but the programme also offers the more traditional 100 Miles, 100km and 75km distances.

Organised by Unique Events & Media that also brings you Brah Yang Trail Summit in March, Prenn has been catching the attention since its inaugural edition back in 2023. Dalat in the southern Central Highlands of Vietnam has no shortage of trail events any more, but Prenn draws appreciation for its emphasis on the basics of trail running, the communities, combined with a solid and pleasant organisation. The event centre, also expo place and finish line for all distance categories, is the Prenn Tea Resort.

The website of the event is incredibly detailed and you can find all you need to know right there. In a nutshell, the 250km race - labeled “The Gods” - has an estimated elevation gain of 11730 hm and a cut-off time of 73 hours. Runners start the adventure at the Kala Lake at lunchtime (13:00) on 10 December . 100 Miles participants also start at the Kala Lake on the 11th at 7 am. They will conquer over 8000 hm and need to complete the distance in 55 hours. Those who thought a few years ago that running in Dalat is ‘easy’ surely have changed their minds by now :-).

The 100km also has a respectable 4500+ hm and 29 hours of cut-off time. Important, this category starts more or less at sunset on Friday at 18:00. The 75km starts at 3 am on Saturday and comes close to 4000hm and a cut-off time has been placed atv 24 hours.

Dalat is accessible by airplane , or you can also arrange overland transport from Ho Chi Minh City. The website also offers lots of options how to reach the Prenn Tea Resort.
