The Rosalia Sprint, the shortest distance at the Rosalia Trail Challenge in Katzelsdorf, packs all of its work into the first twelve kilometres, climbing twice to around 600 metres. Portion out those two ascents well and the long way home is still a run rather than a matter of getting through it.
The loop starts and finishes in Katzelsdorf, and after a little over a kilometre on the level it begins to climb in steps. The first serious stretch arrives at km 2.75: just under two kilometres at nearly 10 percent. A shorter pitch then leads up to a little over 570 metres. You then hand back around 200 metres of height, reaching a dip at km 8.
Out of that dip comes the steepest climbing of the day: 224 metres of gain in just over two kilometres, peaking near 19 percent. One last short rise leads to the high point at km 12. From there the course loses around 300 metres by km 17, and the final five kilometres are practically level.
The Sprint shares its opening with the Pro and the Ultra but spares you their steep third mountain. That does not make it a stroll: just under a third of the course is level, nearly another third is steeply up or down, and between those extremes there is little ground where you can simply hold a pace.

| km 2.8 | 2 km | 9.7 % | 14 % | +190 m | Cat. 3 |
| km 4.9 | 0.7 km | 6.1 % | 7.4 % | +44 m | — |
| km 8.2 | 2.2 km | 10.3 % | 18.7 % | +224 m | Cat. 3 |

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.
Practically all of the 576 metres of climbing sits before km 13, so the load is lopsided: the first twelve kilometres cost far more than the last ten. Run that part on effort rather than pace, and plan to walk the steepest sections of both ascents.
The Sprint is decided on the climb from km 8.2. It comes straight after two kilometres of descending that have loaded your legs rather than rested them, and it is steeper than the first. Take it in a way that lets you pick up the run again at the top.
The trap is the descent between km 12 and km 17. The long drop invites you to push, but emptying your quads here leaves you with no fluid stride for the five flat kilometres at the end. That is where the most time is available, provided you can still run evenly.

Expect somewhere around 2:30 to 3:30 hours, depending on your level. The effort is mostly aerobic but is shaped by the two long climbs, each of which holds you close to threshold for many minutes.
The core of the preparation is hill intervals of about two kilometres at roughly ten percent, two or three repeats per session, using the way back down as a jog recovery. That rehearses the sequence of the race: climb, descent, steeper climb. Practise switching between running and fast walking as well, because on pitches near 19 percent walking is often the more economical choice.
Downhill running matters just as much. Around 15 percent of the course drops steeply, and the long descent from km 12 sets how you reach the finish. Build brisk descents into your long runs and add a few flat kilometres at goal race pace afterwards, so your legs know that transition.
With the race on 10 April, most of your preparation falls between January and March. Put the longest runs in March: 18 to 20 kilometres is enough as long as they hold a good share of the race's climbing.
