Free 16-Week Training Plan for Mallorca by UTMB 20K
Train for limestone climbs, coastal humidity, and runnable island trails across Mallorca.
At 26 km with 1,000 m of elevation gain, this is a fast, punchy distance where speed and hill strength both matter. At 38 m of vertical per kilometer, much of the course is runnable — the plan focuses on building your aerobic cruising speed while preparing you for the steeper sections. The official cutoff is 5 hours, so pace management starts from week one.

Unified race plan · beta
Uses the same load, recovery and taper rules as race discovery, with course-specific climbing only because this course has verified elevation.
Use it for race-effort sessions and race day. Easy runs stay easy whatever the goal; the plan's efforts come from how you run now.
Your starting point
Not stated. The plan assumes a typical starting week for this race and opens at 3h 00m of running.
Fit the plan to your recent training
This schedule opens at 3h 00m of running and 275 m of climbing in week one and peaks at 4h 15m and 925 m in a week; the longest planned outing is 1h 40m. These are prescriptions, not proof of readiness.

Peak week target

4h 15m total training time
Cutoff pressure
Firm cutoff
11.5 min/km average required. At an easy all-day pace the course takes about 5 h of the 5 h allowed.
That leaves little margin: a bad patch, the weather or an intermediate cutoff can decide the day, and more training buys less time on a course like this than it seems.
Training emphasis: rolling aerobic speed, moderate hill repeats, and disciplined pacing.

Effort: Easy; strides strong but relaxed
Start with 10 minutes easy on rolling terrain. Then 6 x 20 seconds uphill strides, strong but relaxed, walking back down between them. Finish with at least 10 minutes easy; the rest of the run is easy on the hills.
Effort: Moderate: controlled reps, stop 1–2 short of failure
No-gym Session A: Bulgarian split squat, single-leg RDL, step-ups (bench/stairs), calf raises, side plank. Quality reps; stop well before failure. If 10 reps feels easy, add weight (backpack/water) so the last 2 reps feel challenging. In peak weeks, keep it short and easy.

About the Mallorca by UTMB 20K course
At 26 km with 1,000 m of elevation gain, this is a fast, punchy distance where speed and hill strength both matter. At 38 m of vertical per kilometer, much of the course is runnable — the plan focuses on building your aerobic cruising speed while preparing you for the steeper sections. The official cutoff is 5 hours, so pace management starts from week one.
This training plan adapts the 16-week structure specifically for 26 km with 1,000 m of elevation gain,
scaling weekly volume and vert targets so your body is ready for race-day demands.
Shorter trail races reward aggressive pacing and strong climbing. The plan emphasises quality intensity — hill repeats, tempo efforts, and race-pace sessions — while building enough endurance to finish strong on tired legs.
Training phases for 20K
The current 16-week schedule has these phases for 26 km and 1,000 m of climbing:
Weeks 1–6 — Base Building: Establish consistent aerobic training and introduce course-like terrain gradually.
Weeks 7–11 — Vert Accumulation: Increase course-specific climbing while rehearsing easy effort and fueling.
Weeks 12–14 — Peak Volume: Practise the longest planned outings and race equipment without adding extra sessions.
Week 15 — Taper: Reduce training load while retaining a small amount of familiar intensity.
Week 16 — Race week: Reduce training and follow the race-day plan.
Pacing a runnable course
At 38 m of vertical per kilometer, much of the Mallorca by UTMB 20K course is runnable.
Training should emphasise aerobic cruising speed — tempo runs on rolling terrain, sustained effort on moderate climbs, and efficient flat-to-uphill transitions.
The biggest risk on a runnable course is starting too fast; practice negative-split long runs to build discipline.
