Ultra-Trail Mount Yun by UTMB UMY 100M

Not doable

· 166 km, +7,400 m · 29.7–41.2 h on your feet · 6 wk easy running after

45 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 2 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 tick “keep a weekly climb” below, so the earlier block builds the terrain this race needs; 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.

What you could change

  • keep stimulus Keep one weekly climbing session, and controlled descents, through the earlier block so Ultra-Trail Mount Yun by UTMB UMY 100M inherits the terrain work instead of starting from zero.
  • change distance Take a shorter distance at the same event as Ultra-Trail Mount Yun by UTMB UMY 100M. It keeps the trip and the entry, and a shorter race costs less recovery while transferring nearly as much preparation.
  • move or replace Look for a similar race later in the window, so Ultra-Trail Mount Yun by UTMB UMY 100M's preparation has the weeks it needs. Find alternatives →
  • drop Leave Ultra-Trail Mount Yun by UTMB UMY 100M for next season.
7,409 m of racing descent

Downhill running causes more muscle damage and slower functional recovery than level running, which is why this model spaces races by descent and duration rather than by distance. There is no validated per-metre dose.

Basis: research

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.
