Faszination Jungfrau-Marathon 42,195 km, 1953 Höhenmeter und 4000 Startplätze, welche jedes Jahr ausverkauft sind. Das sind die Zahlen, die den Jungfrau-Marathon besonders machen. Doch nicht nur diese Zahlen, sondern auch die wunderschöne Umgebung, die es auf der ganzen Strecke immer wieder zu bestaunen gibt, lassen die Herzen höherschlagen. Natur pur! Am Start in Interlaken lässt sich das Ziel bereits erahnen. Der Blick zu der Jungfrau, welche zum berühmten Dreigestirn der Alpen «Eiger, Mönch und Jungfrau» gehört, gibt die Richtung vor. Der Jungfrau-Marathon führt durch viele wechselnde Szenarien – am schönen Brienzersee entlang, durch traditionelle Bergdörfer und schliesslich an einer fantastischen Bergkulisse vorbei. Die einmalige Stimmung, welche auf der ganzen Strecke von Fahnenschwingern, Alphornbläsern und «Trychlern» unterstützt wird, macht diesen Lauf zu einem faszinierenden Ganzen.
