The Drei Zinnen Winter Night Run covers 13 kilometres by night through the wintry landscape around Sexten. The course climbs long and steadily through the first half before falling back to the start. It calls for steady climbing endurance and sure footing on winter ground in the dark.
The Winter Night Run covers around 13 kilometres through the deeply snow-covered Fischleintal (Val Fiscalina) in the Sexten Dolomites, run after nightfall. The entire route follows a well-groomed cross-country ski trail, so the surface is snow from start to finish, and every runner carries a headlamp. The start sits next to Hotel Waldheim in Sexten, from where the course heads up the valley.
A flat opening gives way at kilometre 0.65 to the long climb toward the head of the valley. Over a little more than three kilometres the trail rises at roughly four percent on average, with short ramps reaching about eleven percent. Most of the day's 200-odd metres of gain accumulate before the Talschlusshütte, the turnaround at around kilometre 5.7. Below the Zwölferkofel the field swings back and retraces the same trail down the valley, now mostly gently downhill, so the second half runs faster. A short loop through Moos closes the course at the finish.
The profile is evenly built: one continuous climb out, one long, gentle run back. What makes it demanding is less the gradient than the mix of snow, cold and darkness. The monumental backdrop of the Sexten Dolomites stays largely hidden in the beam of the headlamp, giving the race its own distinctive character.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 0.7 | 3.1 km | 4.2 % | 10.8 % | +130 m | Cat. 4 |
| km 4.3 | 1.3 km | 4.7 % | 5.9 % | +62 m | — |
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.
The elevation sits almost entirely in the first half: a long, even climb of just over three kilometres at about four percent runs from the start, followed by a second, shorter ramp to the high point around kilometre six. It never turns steep, the gradient mostly staying in single digits; the load comes from length, not from the pitch.
Ration the first part so you haven't overcooked it at the top, because the course then descends across the whole second half back to the start. That is exactly where the race is decided: running the descent smoothly and securely on the wintry, dark ground gains more than any surge uphill.
The most common mistake is to force the climbs in the cold night race and then turn tense and uneasy on the way down. Hold a calm rhythm going up and run down controlled, eyes on the lit track ahead.

For a typical age-group runner the 13 kilometres take roughly one to one and a half hours. Snow costs both pace and footing, so finishing times run noticeably longer than over comparable distances on firm ground.
The effort is steadily aerobic for most of the race. The first half is one continuous, moderate climb to the head of the valley, the second a long, gently descending run-out. The profile asks for almost no anaerobic spikes, but it does demand pacing discipline: attack the climb to the Talschlusshütte too hard and you arrive at the turnaround without the legs to actually run the easy way back.
The decisive section is the unbroken ascent over the first five kilometres or so. Here an economical uphill technique on soft ground pays off. Train longer, relaxed climbs at moderate intensity and get used to running on snow, where push-off softens and your stride shortens.
Two specifics belong in your preparation: running in the dark with a headlamp, so you can read the surface and pick your line confidently inside a narrow beam, and the cold. Short sessions at low temperatures train both your breathing and your clothing choices. Controlled downhill running on slippery ground rounds it off, helping you keep the long descent smooth and free of falls.
