Mallorca by UTMB 20K

Not doable

· 26 km, +1,000 m · 3–4.2 h on your feet · 3 wk easy running after

38 m of climb per km — steep enough that most runners hike the longer climbs.

Course, cutoffs and race-day guide

Only 4 weeks before it, where your build needs 9 (the generic figure is 12).

What would change this: 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.

the dark row marks weeks with real climbing in them

3 wk building for this race
9 wk is a full build for you (shorter than the generic 12 weeks because you run 45 km a week, far above the 18 km this distance assumes)
1 wk tapering, racing or recovering — building nothing

What you could change

In the order most runners prefer: keep the trip if you can, drop the race last.

  • keep stimulus Keep one weekly climbing session, and controlled descents, through the earlier block so Mallorca by UTMB 20K inherits the terrain work instead of starting from zero.
  • change distance Take a shorter distance at the same event as Mallorca by UTMB 20K. 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 Mallorca by UTMB 20K's preparation has the weeks it needs. Find alternatives →
  • drop Leave Mallorca by UTMB 20K for next season.

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.
