The start point is in front of the federal building in the city of Bern, capital of Switzerland. the first few kilometers are through the old town of Bern with its fountains and sandstone houses. Through the „Matte Quartier“ you leave the city center along the river „Aare“ and climb up to the public Zoo „Dälhölzli“ where you already enter a forest and the tarmac turns into gravel. Crossing the Aare for the second time you will start gaining some altitude up to the „Hausberg Gurten“ with a super view over the whole city. Enjoy the gravel descent into the Gurten valley and again up to the second guardian the Ulmizberg or „Ulmizer“. Up and along the „Lengenberg chain“ you will reach Riggisberg. Soon you enter the bike-path to Schwarzenburg. The next eye-catcher is the Guggershörnli before we start the biggest climb to the Voralpenpass Gurnigel (1608m). You will be rewarded with a long gravel descent to the city of Thun, where you will find many options to re-supply. You’ll climb up to the point where the INFERNO TRIATHLON road track joins you towards Beatenberg (Schlucht) down and along the bay of lake Thun back to Thun. Forests and farm fields will guide your way up and down touching the area of Emmental (famous cheese) back to Bern again. Before finishing at Bundesplatz, have a coffee stop at tac tac cycling. (Turn right to Gotthelfstraße when you are on the Viktoriastraße in Bern.)
