The Light Trail is the shortest race at the Belgenbachtrail in Monschau, a 4.5 km loop in the Belgenbach valley. Short does not mean free here: the ground can be muddy and slippery, and the final stretch before the finish climbs for about a kilometre.
Start and finish are at the Wanderhütte Belgenbachtal, so the loop ends where it began. The first kilometre sets the rhythm: a short rise to the highest point of the course, then down into a dip and straight back out. After that it stays almost level until about km 2, the calmest part of the race.
From km 2.2 the course falls steadily for around a kilometre, and all of that height has to be won back. The decisive climb starts at km 3.2, a little over a kilometre long and runnable at 4.5 percent on average, even though it steepens noticeably along the way. From the top only a few hundred metres remain to the line.
The setting is the Belgenbach valley in the Rur area of the Eifel, and the organiser itself warns of mud and slippery sections. The Belgenbachtrail is in its 13th edition. There is no parking at the hut, and number collection and awards are at MUK Konzen, so plan your arrival around two locations.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 0.1 | 0.4 km | 3.2 % | 3.8 % | +11 m | — |
| km 1 | 0.4 km | 4.5 % | 7.3 % | +17 m | — |
| km 3.2 | 1.1 km | 4.5 % | 8.5 % | +48 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.
The loop asks for discipline straight away: the highest point comes after just 500 metres, and the dip follows immediately. Do not let that turn into a sprint. After the short climb at km 1 comes the almost level section, and that is where you settle into race pace.
The drop from km 2.2 feels like free time and is the real trap. Run it flat out on slippery ground and you reach the foot of the final climb with a high pulse and heavy legs. Keep it loose and safe, with short steps wherever it turns muddy.
The Light Trail is decided on that last kilometre before the crest. Most of it is too gentle to justify walking, so enter at km 3.2 at an effort you can carry to the top. Only push once the last steeper metres are behind you.

Expect roughly 30 to 45 minutes. That is a hard, sustained effort near threshold, with short spikes on the rises and no section where the race truly lets up. Endurance matters less here than the ability to rebuild pressure after a fast descent.
Build your preparation around the final climb. The key session is hill repeats of about a kilometre on a moderate gradient, three to five times, at a pace just beyond comfortable. Run a quick downhill stretch before each repeat: that rehearses exactly the switch the race demands from km 3.
The 7 March date puts your build in winter, and the organiser describes the ground as partly muddy and slippery. So move at least one session a week onto soft paths instead of tarmac. On a slippery descent, a lack of trust in your footing costs more than a lack of strength, and you should have tested grippy shoes on that kind of ground well before race day.
Add an easy aerobic run over hilly terrain and short sessions on rolling ground where you get back up to speed right after each crest. This distance needs no more than that. Long runs give you less on the Light Trail than clean, hard kilometres on a hill.
