UTH50 is the long Saturday loop of Albside - Up The Hill: roughly 2,000 metres of climbing over Käsental, Heersberg, Steinberg and Tieringer Hörnle, with the two hardest ascents held back for the very end. Getting it right means preparing to power-hike steep ramps on legs that have already done most of a day.
Start and finish share the event area in Albstadt-Margrethausen, and the loop switches between trail, gravel and asphalt along the way. The first two kilometres rise steadily; after that the height comes in short, steep pieces. Just past kilometre 9 sits a half-kilometre that averages close to 20 percent. From kilometre 16.7 the course then gains about 200 metres in a kilometre and a half.
Through the middle the race settles down. After a low section around kilometre 22, two climbs bring you back up to roughly 900 metres. From there the loop stays high for about eight kilometres before a long descent drops it back into the valley.
UTH50 is decided in its final sixth. Shortly after kilometre 44 the biggest single climb of the day begins, gathering around 270 metres of ascent in under two kilometres. Another ramp from kilometre 47.7 has pitches above 30 percent, and only then does the trail run down into the event area, closing a loop that has taken in Käsental, Heersberg, the Steinberg aid point and Tieringer Hörnle.

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.
Close to 40 percent of the loop is steep, up or down, and barely a tenth is flat. So hike the ramps from the start, including the early ones you could still run on fresh legs. Every climb you run in the first half is one you pay for later.
The long high section from kilometre 30 is where you set up the finish: run evenly, eat and drink, and resist the urge to make up time. Use the four aid points before hunger arrives, not after.
The real trap is the descent before kilometre 44. Let it run and you reach the biggest climb of the day with burnt quads. Brake with control, take the last two ramps at a rhythm you can hold to the top, and save your running for the short drop to the finish.

For a typical age-group runner, UTH50 takes something like six to nine hours. The effort is long and aerobic, but broken again and again by short, very steep pieces where your heart rate climbs even though you are walking. Your training has to cover both: hours on your feet and repeated steep hiking.
Because the hardest climbs sit in the final sixth, long runs with the climbing at the end are the most important single session. On weekend long runs, put the steepest hills deliberately into the last hour and practise a brisk hands-on-thighs hike there until it still feels strong when you are tired.
Downhill running matters just as much. Nearly a fifth of the course drops steeply, and the long descent before the final climb decides what legs you arrive there with. Build steep descents into your runs regularly so your muscles get used to the braking work.
The race falls in late April, which puts your build-up in winter and early spring. Still do the long sessions on a mix of trail, gravel and asphalt, and wear the mandatory kit on them so its weight and fit hold no surprises on race day. Test your fuelling on the same runs; over that many hours it shapes how the finish goes.
