Südtirol Drei Zinnen Alpine Run.
The Südtirol Drei Zinnen Alpine Run climbs from Sexten to the Dreizinnenhütte in the Dolomites UNESCO World Heritage site. The route moves from valley paths into high-alpine terrain and concentrates its decisive ascent in the middle section; preparation therefore needs more than endurance, with long uphill running and hiking at altitude at its centre. Also known as Drei Zinnen Alpine Run and Corsa delle Tre Cime.

Südtirol Drei Zinnen Alpine Run: Course, Elevation & Route Profile
The start is at Haus Sexten in the valley, followed by a relatively calm opening. After a few smaller undulations, the main climb begins at about kilometre 6.6: over almost eight kilometres the route gains roughly 1,100 metres, averaging about 14 percent with much steeper pitches. This is not one uniform forest-road climb, but a long sequence of steep mountain paths and short sections where you have to find your rhythm again.
Higher up, the landscape becomes part of the race itself. The route passes the Talschlusshütte, Zsigmondyhütte and Büllelejochhütte in the Fischleintal before finishing at the Dreizinnenhütte. The finish sits at 2,405 metres, while the course reaches roughly 2,575 metres at its highest point; weather and footing can therefore feel distinctly alpine compared with the start in Sexten.
The organiser presents the race as a mountain run through the Sexten Dolomites and expects up to 1,000 runners from more than 20 nations. This edition's course is slightly changed from earlier years. The final ramp comes after the long central climb and calls for one more period of controlled uphill movement, not an all-out sprint after fatigue has set in.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 0.6 | 0.7 km | 3.2 % | 5.6 % | +22 m | — |
| km 3 | 1.2 km | 6.8 % | 10.8 % | +81 m | Cat. 4 |
| km 6.6 | 7.8 km | 14 % | 32.7 % | +1,098 m | HC |
| km 17 | 0.4 km | 15.7 % | 21.4 % | +63 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.
How to pace Südtirol Drei Zinnen Alpine Run.
Start under control
Treat the race as three different tasks: a controlled valley opening, a long central climb and a focused finish to the hut. The first kilometres should not tire you; on the gentler opening, calm running is more useful than a gain you will pay back on the mountain anyway.
Hold your rhythm
The decisive section lies roughly between kilometres 6.6 and 14.5. That is where almost all of the profile's climbing sits, with 41 percent of the route moderately uphill and another 36 percent steep uphill. Switch between running and brisk hiking before the gradient forces you to. That keeps the effort even instead of turning it into short, costly surges.
Spend what is left
The main trap is believing the finish is close after Büllelejoch. A steep final ramp remains, and above 2,400 metres the body forgives overreaching less readily. Shorten your stride, keep strength for the last metres and treat a change to cold, fog or wind as part of the pacing plan.
Training plan for Südtirol Drei Zinnen Alpine Run: 12-week build
Build the base
Depending on your level, allow roughly two and a half to four and a half hours for the race. The demand is predominantly aerobic but heavily uphill: running and brisk hiking alternate, while altitude further limits the reserve you can draw on.
Train race pace
Build long mountain sessions with at least 90 minutes of continuous ascent. The key is not only maximum gradient but the ability to keep walking or running efficiently after an hour. Add shorter repetitions on steep ramps, while also practising the switch from running to hiking without an abrupt surge.
Rehearse the course
The decisive phase needs strength endurance and secure footing on mountain paths. Train long climbs on changing surfaces, controlled downhill movement under fatigue, and hiking technique; poles should not be part of your race plan because the 2026 rules do not allow them.
Arrive fresh
In mid-September conditions can change from a mild valley start to cold, windy high-alpine weather. Get used to layers and gloves, make sensible weather decisions, and include some long sessions at altitude if possible. Your preparation should reproduce the final climb after substantial gain, not just a fresh uphill sprint.
