Preparation
A realistic 12-week training plan for a 7-day Dolomites trek: weekly mileage, ascent, pack-loaded hikes, leg strength and the stair-machine sessions that actually transfer.

A Dolomites hut-to-hut trek is not a marathon — it's seven consecutive days of 500–1,200 m ascent with a pack on, often at 2,000–2,800 m altitude. The body that fails on day three is almost always the one that did long flat walks instead of focused ascent training.
Be honest about the load. A typical Alta Via day is 12–16 km, 700–1,100 m ascent, 600–1,000 m descent, 5–7 hours of moving time, with a 7–8 kg pack. Day after day, with imperfect sleep in a dormitory and altitude up to 2,800 m on the passes.
The two things that break people are descent quad fatigue (everyone trains uphill, almost nobody trains downhill) and lower back fatigue from the pack. Both are fixable in 12 weeks.
Build the volume without intensity. Goal: comfortable walking 3 hours with a 5 kg pack by week 4.
Switch the long walk to climbing-specific. This is where the trek is actually won.
Now train the pattern of consecutive days that the trek imposes.
Cut volume by 50%. Two short walks early in the week, full rest Thursday–Friday. Fly in slept, hydrated, and with fresh legs. The training is done — the last week is for absorbing it.
Six weeks: skip the base phase, start at week 5. Most people doing this still finish a 7-day trek, but pay for it with sore quads after the first big descent. Four weeks: realistic only if you're already fit from another sport with leg involvement (cycling, running, skiing). Less than that and you're not training — you're hoping.
Comfortable walking 4–5 hours with a 7 kg pack over 700–900 m of ascent. That's the typical Alta Via day, repeated 7 times. Twelve weeks of focused training takes most reasonably active people there from scratch.
Stair machine or steep treadmill with the pack on. Mimics the sustained low-gear effort of an Alpine ascent more accurately than running or cycling. 30 minutes twice a week is enough.
Find a hill you can descend repeatedly and do it. Quads will be sore for 48 hours the first few sessions — that's the adaptation. Trekking poles help, but training the eccentric strength is what saves your knees on the 1,000 m descents.
If you already cycle, run, ski-tour or hike regularly — yes, probably. If you sit at a desk and walk to the bus — you'll finish, but in real pain by day three. Twelve weeks of training is the difference between enjoying it and surviving it.
