Vietnam Highlands Trail by UTMB 100K Langbiang

Not doable

· 104 km, +5,533 m · 19.7–27.4 h on your feet · 6 wk easy running after

53 m of climb per km — a hiking-and-running day; only the front of the field runs the climbs.

Course, cutoffs and race-day guide · Training volume does not certify the technical alpine skills, self-support or intermediate cutoffs this race asks for: check them on the race page.

Only 14 weeks before it, where your build needs 24.

What would change this: build your long run to about 28 km before the block begins, or finish a 50–80 km race first; if your longest recent run is already longer than 22 km, say so under “your running”; or if you have raced this distance before, say so under “your running” — an experienced runner needs a shorter build than the generic one; or a higher current weekly volume shortens the build this race needs; or a shorter distance at the same event, or a later edition.

One coherent season: each demanding race gets its own build, taper and recovery; shorter races are placed inside a build. Recovery spacing and carry-over are reviewed product conventions calibrated against our reference plans, not physiological measurements. Planning guidance from course facts and your stated training — not medical or coaching advice. Recovery spacing, how much preparation carries over, and how many climbing weeks a course asks for are our own reviewed conventions — inspectable, and not measurements of your physiology.
