One lap of the Loiberg is the shortest way to run the Monte Loi Trail Run. Over 4.6 km the course drops away first and then climbs for a long stretch, which turns a short race into a test of how hard you can run for a good half hour without fading on the hill.
The Monte Loi Trail Run takes place on the Loiberg near Breitenfeld an der Rittschein, in 2027 for the second time. There is one loop, and you decide at registration how often to run it. Choose a single lap and you see every section exactly once.
The first few hundred metres are almost level, then the course falls about 60 m to the lowest point of the lap at around km 1.4. The counterpart follows immediately: from km 1.6 the longest climb wins almost all of it back over 1.35 km. It averages a moderate 4.6 percent, with a brief spell near 13 percent in its middle section.
After that the course stays high and turns rolling. A second, much shorter rise leads to the highest point, from where the lap runs gently downhill back to where it began. The total comes to just under 90 m of climbing, while the organiser reckons on about 100. Only around a sixth of the lap is flat.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 1.6 | 1.4 km | 4.6 % | 12.7 % | +62 m | — |
| km 3.6 | 0.4 km | 3.4 % | 5.2 % | +13 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.
Over a single lap there is no reason to save anything, but there is a clear order of business. The descent arrives before your heart rate has settled, and it hands you speed almost for free. Run it quick and relaxed without forcing it: the seconds you squeeze out there are small next to what they cost you afterwards.
The race is decided between km 1.6 and km 3. That is eight to twelve minutes, too short for any recovery to repair an overcooked start. Enter the climb just below threshold, work cleanly through the steep middle and lift the effort only once the gradient eases.
The biggest trap is coasting at the top. After the climb the rolling section feels like a break, yet it is the fastest stretch for anyone with legs left. Push through the short rise after km 3.5; the last 500 m fall gently and belong to your finishing kick.

Expect to race for about 25 to 40 minutes. That is an effort around and just above threshold in which you never really recover, and the abrupt change from downhill to uphill drives your heart rate up within minutes. An aerobic base matters, but at this length the deciding factor is how hard you can hold on.
The key session is hill intervals of three to six minutes on a slope that resembles the Loiberg climb: moderately steep with a steeper spot in the middle. Run them by feel close to your 5K effort and build towards about 20 minutes of hard uphill work per session. The last repetition should be the strongest.
Just as important is the transition, because the race demands it after barely a kilometre. In training, link a quick downhill stretch straight into a climb: your quads have just been braking and must immediately start pushing. Any hill of about 60 m will do, and two to four rounds already make it a serious session.
The 17 April date places your build in January to March. Eight weeks of focused work are enough for this distance if you already run regularly. In the final week keep things short and fast so you reach the start line fresh.
