Free 16-Week Training Plan for Wildstrubel by UTMB Wild 70
Train for high-mountain terrain, point-to-point logistics, and late-season alpine weather.
At 72 km with 4,600 m of elevation gain, this is an ultra-distance effort that demands careful fueling, pacing, and mental resilience. With 64 m of vertical per kilometer, expect significant hiking sections — training should emphasise power-hiking and efficient descending. The official cutoff is 17.5 hours, so pace management starts from week one.

Terrain autopilot
Find a matching route near you
We'll look for a loop near you that matches your next run (1h 10m · ~6.5 km · +475 m)
and rehearses the 64 m/km demand of Wild 70.
Terrain intel
Expect long pass climbs, runnable alpine meadows, rocky descents, and high exposed sections around Gemmi, Rawyl, and the Wildstrubel hut.
Weather & kit
September can be ideal, but cold rain, fog, and early snow are realistic above 2400 m.
What this plan focuses on
Build hike-run transitions on sustained climbs.
Practice technical downhill running after long climbs.
Prepare for cold-weather layering without slowing aid-station flow.
Dial in fueling for remote sections between support points.
Use course-specific long runs to rehearse steady pass-to-pass effort.
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 7h 25m of running.
Fit the plan to your recent training
This schedule opens at 7h 25m of running and 1,375 m of climbing in week one and peaks at 11h 25m and 3,550 m in a week; the longest planned outing is 5h 05m. These are prescriptions, not proof of readiness.

14.6 min/km average required. At an easy all-day pace the course takes about 18.5 h of the 17.5 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.For a first time, Wildstrubel by UTMB Wild 55 on the same weekend is the safer choice.
Training emphasis: sustained climbing, downhill resilience, and efficient hike-run transitions.

About the Wildstrubel by UTMB Wild 70 course
At 72 km with 4,600 m of elevation gain, this is an ultra-distance effort that demands careful fueling, pacing, and mental resilience. With 64 m of vertical per kilometer, expect significant hiking sections — training should emphasise power-hiking and efficient descending. The official cutoff is 17.5 hours, so pace management starts from week one.
This training plan adapts the 16-week structure specifically for 72 km with 4,600 m of elevation gain,
scaling weekly volume and vert targets so your body is ready for race-day demands.
Ultra-distance trail races require a different approach to training than road marathons. Time on feet matters more than pace, and vertical accumulation is as important as distance.
This schedule includes back-to-back long days in selected loading weeks to rehearse moving on tired legs. It also includes regular easier weeks.
Training phases for Wild 70
The current 16-week schedule has these phases for 72 km and 4,600 m of climbing:
Weeks 1–6 — Base Building: Establish consistent aerobic training and introduce course-like terrain gradually.
Weeks 7–10 — Vert Accumulation: Increase course-specific climbing while rehearsing easy effort and fueling.
Weeks 11–13 — Peak Volume: Practise the longest planned outings and race equipment without adding extra sessions.
Weeks 14–15 — Taper: Reduce training load while retaining a small amount of familiar intensity.
Week 16 — Race week: Reduce training and follow the race-day plan.
Preparing for steep terrain
At 64 m of vertical per kilometer, the Wildstrubel by UTMB Wild 70 course is significantly steeper than average.
In this plan the uphill sessions and the climb-and-descent rehearsals are where to practise power-hiking (with poles, if you will race with them) and steep, controlled descending, and the strength sessions carry the eccentric work for your quads.
Practice eating and drinking on steep climbs — this is where many runners lose time to nausea and energy dips.
