Mayrhofen Ultraks Zillertal Training Plan & Preparation
The Z101 packs 101 kilometres and roughly 7,500 metres of climbing into a single loop through the Zillertal — an ultra defined not by its distance but by the sheer density of its climbs. Seven long ramps, several beyond the HC category, leave almost no flat ground. Preparing for the Z101 means training above all for hours of climbing and descending with barely any recovery.
Course & Elevation
The Z101 is the flagship of the Mayrhofen Ultraks Zillertal: 101 kilometres and 7,600 metres of climbing on one vast loop through the Zillertal Alps, starting and finishing in the centre of Mayrhofen. The route travels high alpine trails, mountain refuges serve as waypoints along the way, and the race carries ITRA and UTMB points.
The profile is uncompromising from the first hour. The opening giant begins at kilometre 2.9, an 8.6 kilometre climb gaining 1,264 metres, followed from kilometre 20.8 by the longest single block of the day: nearly ten kilometres of ascent worth 1,462 metres. The second half escalates rather than relenting. From kilometre 52.5 the course climbs 1,290 metres in just over six kilometres at an average gradient above 20 percent, from kilometre 63.3 another 869 metres, and from kilometre 72.3 a further 838 metres on similarly steep slopes. Even between the named climbs the terrain stays restless, with almost 1,000 additional metres of gain hidden outside the counted ascents.
Barely 8 percent of the distance is flat, nearly a third is steep uphill and almost another third steep downhill. The Z101 is a high-mountain ultra in the fullest sense and the most demanding format of the event.
Pacing Strategy
More than 60 percent of the course is steep up or down — flat running barely exists, so plan in climbs and descents from the gun, not in kilometre splits. The brutal wall right after the start (around 300 metres of climb in 800 metres) is a trap: hike it, don't run it, or the race is over before it begins.
The two HC climbs inside the first 30 kilometres lift you above 2,700 metres — hold a pace you could still hike after eight hours. The Z101 is decided in the final third: from kilometre 52 three hard climbs (km 52, 63 and 72) with over 20 percent gradient hit already-tired legs. Overspend before them and you crack here.
Save something for the steep descents — at nearly 30 percent downhill grade they drain the quads and demand focus right to the finish.
12-Week Preparation
At 101 kilometres with 7,600 metres of climbing, age-group runners should expect to be moving for 20 to 30 hours, which for most means running through at least one full night. The character is a long, low-intensity aerobic effort in which pacing restraint, fuelling and muscular durability decide the outcome far more than speed ever will.
The race is decided on the steep climbs of the second half. From kilometre 52.5 onward, three climbing blocks totalling around 3,000 metres of gain arrive on slopes that partly average above 20 percent, all with 50-plus kilometres already in your legs. Efficient, energy-saving uphill hiking is the single most important skill here, because at those gradients almost nobody is running. Just as critical are the nearly 7,500 metres of descent, which load the quads eccentrically for many hours.
Your preparation therefore needs high weekly vertical volume with long, steady climbs and deliberately completed long descents, ideally structured as back-to-back days to build fatigue resistance. Treat fast uphill hiking as a discipline of its own and practise it on genuinely steep ground. Test your race nutrition in the longest training sessions, because over 20-plus hours the stomach limits performance as much as the legs do. Schedule at least one long outing in alpine terrain that extends into darkness, so headlamp, equipment and mind are all accustomed to moving through the night before race day asks it of you.

Climb categories follow the road-cycling convention and rate the terrain itself — length and gradient — regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
