Intense is the long loop at the Grenzgänger Wandermarathon & Trail Run: from Weißbach bei Lofer it strings together five climbs, tops out near 1,450 metres and comes all the way back down. Getting ready for it means preparing less for 30 kilometres than for the last big climb after kilometre 17 and the long descent that follows.
The first two kilometres or so are flat, then the hardest stretch of the day starts at once: more than 500 metres of climbing in one go, averaging 16.6 percent. After a gently falling section, the second climb sets in at kilometre 7.6, steepens towards its end and tops out at about 1,370 metres. The third and shorter one follows at kilometre 12, before the course drops to around 1,000 metres by kilometre 16.5.
This is where the second half begins, and it settles the race. After a short ramp, the climb to the high point starts at kilometre 17.3, a little over 400 metres of gain in 3.5 kilometres. From kilometre 22 there are nine kilometres of almost pure descent, nearly 800 metres back to where you started.
The Grenzgänger links Weißbach bei Lofer with Ramsau bei Berchtesgaden, and the Naturpark Weißbach with the Berchtesgaden National Park. Every Trail Run variant starts and finishes in Weißbach, and Intense is the longest of them. Four aid stations divide the day: Goldener Zweig, Litzlalm, Kammerlingalm and Kallbrunnalm.

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.
More than half of the course is steep, up or down, and only six percent is flat. Kilometre splits are no use here: steer by effort and hike the steep passages from the start, even while you could still run them.
The biggest trap comes early. The first climb arrives on fresh legs after two flat kilometres, and keeping up there instead of settling in is a debt you pay hours later. That one stretch holds a third of all the ascent, yet when it ends you have not covered even a fifth of the distance.
The race is decided from kilometre 17 on. The climb to the high point needs legs that can still push evenly, and the long descent comes right after it. Arrive at the top empty and you lose more time going down than you did going up, because your quads can no longer absorb any speed. Treat the four stations as fixed points for eating and drinking, so that this reserve is still there.

Age-group runners spend roughly four and a half to six and a half hours on this loop. The effort is mostly aerobic but never steady: long spells of steep hiking alternate with descents that bring the heart rate down while still working the muscles hard.
The key stimulus is climbing on tired legs. Build long sessions so that a solid climb sits in the second half rather than at the start. Two climbs of 400 to 500 metres in one day, the second after several hours on your feet, come closest to the race. Practise a strong hiking stride with hands on your thighs, or with poles if you plan to use them and they are allowed.
Downhill running matters just as much. Only quads that know this braking work survive the final nine kilometres, so add fast descents regularly, ideally straight after long climbs when the legs are already tired, and back them up with strength work such as lunges and single-leg squats.
With the race on 10 July, your longest sessions fall in May and June. Use them as a rehearsal for fuelling too, on the move and spaced the way the stations will be. Altitude hardly matters at a maximum of about 1,450 metres; steepness matters all the more.
