GT85 ist das Ultra-Format des Grand Trail des Lacs & Châteaux (Summer): gut 87 Kilometer ab der Skipiste von Ovifat, über Waldpfade am Rand der Hohen Venns, vorbei an Seen und Burgen der Ostbelgischen Ardennen. Entschieden wird er nicht an einem großen Pass, sondern an Dutzenden kurzer, sehr steiler Rampen und technischer Abstiege.","GT85 is the ultra of the Grand Trail des Lacs & Châteaux Summer edition: some 87 km from the Ovifat ski slope along forest paths at the edge of the Hautes Fagnes, past the lakes and castles of the eastern Belgian Ardennes. It is decided not on one big pass but on dozens of short, very steep ramps and technical descents.",{"de":222,"en":223},"Start ist um fünf Uhr morgens an der Skipiste von Ovifat; hier liegt auch das Ziel. Die Strecke verläuft fast ohne Asphalt über Waldwege und Singletrails durch die Gegend um Robertville, Malmedy, Stavelot und Xhoffraix. Der Veranstalter nennt die Warche-Schlucht mit der Route des Crêtes, die Burg Reinhardstein und Naturschutzgebiete, deren Pfade er mit Mittelgebirgstrails in Frankreich vergleicht.\n\nDas Profil zeigt rund 3.220 Höhenmeter, verteilt auf ein ständiges Auf und Ab. Die ersten 27 Kilometer bleiben vergleichsweise wellig. Danach folgen die markanten Anstiege dicht aufeinander: bei km 28 und km 30 zwei Rampen mit je rund 105 Höhenmetern, bei km 30 mit durchschnittlich 16 Prozent. Der längste Anstieg beginnt bei km 45,6 mit 2,9 Kilometern und über 200 Höhenmetern.\n\nIm letzten Drittel wird es noch einmal härter: Zwischen km 57 und km 70 liegen vier Anstiege, darunter zwei kurze Wände bei km 66 und km 69 mit 17 bis 19 Prozent Durchschnitt und Spitzen über 35 Prozent. Die Schlussrampe zur Skipiste ist das gemeinsame Finale aller Strecken des Wochenendes.","The start is at 5 a.m. at the Ovifat ski slope, which is also the finish. The route has very little asphalt and runs on forest roads and singletrack around Robertville, Malmedy, Stavelot and Xhoffraix. The organiser highlights the Warche valley with its Route des Crêtes, Reinhardstein castle and nature reserves whose paths it compares to French mountain trails.\n\nThe profile shows about 3,220 m of ascent spread over constant up and down. The first 27 km stay comparatively rolling. After that the notable climbs come close together: two ramps at km 28 and km 30 with about 105 m each, the second averaging 16 percent. The longest climb starts at km 45.6, 2.9 km with more than 200 m of gain.\n\nThe final third is harder still: between km 57 and km 70 there are four climbs, including two short walls at km 66 and km 69 averaging 17 to 19 percent with pitches above 35 percent. The last ramp up the ski slope is the shared finale of every race of the weekend.",{"de":225,"en":226},"Die ersten 27 Kilometer laden zu einem zu hohen Tempo ein, weil sie wellig und gut laufbar wirken. Wer hier Reserve lässt, hat sie für den Abschnitt ab km 28, in dem die steilen Rampen dicht aufeinanderfolgen. Gehe die Anstiege über zehn Prozent konsequent und kraftsparend, statt sie zu laufen.\n\nRennentscheidend ist das Stück zwischen km 57 und km 70: vier Anstiege mit zusammen über 500 Höhenmetern kommen für die meisten Läufer erst nach vielen Stunden Belastung, zwei davon als Wände mit Spitzen über 35 Prozent. Hier bricht die Pace der meisten Läufer ein.\n\nDie größte Falle sind die technischen Abstiege. Wurzeln, Fels und nasse Waldpfade kosten Oberschenkelmuskulatur, und wer bergab früh zu schnell läuft, hat im letzten Drittel keine Kraft mehr für die kurzen, steilen Gegenanstiege.","The first 27 km tempt you into too high a pace because they feel rolling and runnable. Hold back there and the reserve is still available from km 28, where the steep ramps come in quick succession. Power-hike every climb above ten percent rather than running it.\n\nThe race-deciding section is km 57 to km 70: four climbs totalling more than 500 m arrive for most runners only after many hours of effort, two of them walls with pitches above 35 percent. This is where most runners' pace collapses.\n\nThe biggest trap is the technical descending. Roots, rock and wet forest paths eat the quads, and whoever runs the early descents too fast has nothing left in the final third for the short, steep counter-climbs.",{"de":228,"en":229},"Der GT85 ist eine Belastung von gut sieben Stunden an der Spitze bis zum Zeitlimit von 18 Stunden. Die Anforderung ist kein gleichmäßiger Bergaufstieg, sondern ein ständiger Wechsel aus kurzen, sehr steilen Rampen, technischen Abstiegen und flacheren Waldpassagen.\n\nDie Grundlage bilden lange Läufe von fünf bis sieben Stunden auf welligem Gelände, möglichst auf Waldpfaden mit Wurzeln und Fels. Baue in diese Läufe gezielt Wiederholungen an steilen Hängen ein und übe das kraftsparende Gehen mit hohen Steigungen. Ein Back-to-Back-Wochenende mit zwei langen Einheiten bereitet auf die späte Rennphase vor.\n\nTrainiere das Bergablaufen bewusst: exzentrische Kraft für die Oberschenkel, Sprungkraft und technische Abstiege in müdem Zustand. Das entscheidet über das letzte Drittel, in dem die steilsten Rampen liegen.\n\nMitte Mai kann es in den Hohen Venns kühl und nass sein, der Start um fünf Uhr erfordert eine Stirnlampe. Übe Verpflegung und Ausrüstungswechsel bei langen Läufen, denn es gibt nur fünf Verpflegungsstellen auf 87 Kilometern.","GT85 is an effort of just over seven hours at the front up to the 18-hour time limit. The demand is not a steady mountain climb but a constant alternation of short, very steep ramps, technical descents and flatter forest sections.\n\nThe foundation is long runs of five to seven hours on rolling terrain, ideally on forest paths with roots and rock. Build steep-hill repeats into those runs and practise economical power-hiking on high gradients. A back-to-back weekend of two long sessions prepares you for the late phase of the race.\n\nTrain descending deliberately: eccentric quad strength, plyometrics and technical downhills on tired legs. That decides the final third, where the steepest ramps sit.\n\nIn mid-May the Hautes Fagnes can be cool and wet, and the 5 a.m. start requires a headlamp.

They are runnable, and whoever still has strength there gains a lot of places.\n\nThe trap is the roots and wet passages on the descents.
