Ultra-Trail Kosciuszko by UTMB Kosci50

Course, cutoffs and race-day guide

Only 8 weeks before it, where your build needs 13.5 (the generic figure is 16).

What would change this: 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.
