Do your races work together? Every verdict comes from the course facts and from how much of one race's preparation carries over to the next. Nothing is saved unless you keep it in your account: your season lives in this page's address.

Your running: 45 km/week · 22 km longest · 5 days · mixed terrain · some experience

Your race fits the calendar, but the Desert RATS Trail Running Festival by UTMB 100K block cannot build its climbing to the course's in the weeks it has. Its card says what leaves more margin.

This week · Off-season base

Between blocks the season runs our general Evergreen plan, built from the weekly volume and days you entered. You do not need to have used it before.

5h of running

  • Tue Fartlek 45m · Controlled hard efforts by feel; do not chase a pace. Jog to recover between them.
  • Wed Full-body strength (bodyweight) 30m · Controlled reps. Stop 1–2 before failure.
  • Thu Easy run + strides 45m · Easy + short fast strides at end
  • Fri Easy run 45m · Easy — fully conversational
  • Sat Long run 2h · Easy and conversational
  • Sun Easy run 45m · Easy — fully conversational

Next week: Off-season base · 5h

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.
