Prenn Trail Summit 2026

Prenn Trail Summit 2026 is a five-day mountain-running festival in Da Lat, Lam Dong Province, from 9 to 13 December. The fourth edition is organised by Unique Events & Media in its Unique Race Series, with Tea Resort Prenn at the foot of Prenn Pass as the principal expo and finish hub. Courses traverse highland villages, pine forest, rugged slopes and valleys. Some of the long-distance races start at different venues.

The eight official race categories are 3K, 10K, 25K, 55K, 75K, 100K, 100 miles and 250K. The advertised 10K is approximately 12 km on the ground with 550 metres of ascent; the 100K course is approximately 103 km with 4,546 metres of ascent. The 25K has around 1,289 metres of climbing, the 55K 2,485 metres, the 75K 3,989 metres, the 100-mile course 8,020 metres, and the 250K approximately 11,738 metres. The latter is among Vietnam's longest organised trail-running challenges. ARC's distance registry cannot precisely represent 55K, 75K, 100 miles or 250K, so these remain explicitly documented here rather than being mapped to misleading alternatives.

Race-week activities begin with the expo, bib collection and equipment checks on Wednesday 9 December. The 250K starts at Kala Lake at 13:00 on Thursday 10 December, with a 73-hour cut-off. The 100-mile race starts from Kala Lake at 07:00 on Friday 11 December with a 55-hour cut-off. The approximately 103K course begins at Bookabang Village Hall at 18:00 that Friday, with a 29-hour cut-off. The 75K and 55K follow on Saturday, with shorter courses on Sunday 13 December. Participants should check the latest official timetable, mandatory gear and transfers because starts differ between categories.

Prenn is part of the Asia Trail Master Grandmaster Quest programme: finishers of qualifying long distances can earn points under its rules. The TORX eXperience partnership also lists an allocation of 20 direct places for TOR330 2027 associated with finishers of the 103K, 100-mile and 250K races, subject to conditions.

Entries are sold via the organiser's official registration partner, with regular fees varying by distance. The published registration closing date is 30 November 2026 on EnjoySport, although another race calendar displays 1 December. Travelling runners should arrange accommodation and transport in Da Lat, confirm their start location and read the current athlete guide before heading into remote mountain terrain.
