Starting in the town of Adliswil, ascend almost 300 meters to the top of Zurich’s most frequently tested climb. The slope starts gently enough as you wind your way through the city at the base of the hill. The gradient kicks up at the ‘true’ start of the climb, then slowly stabilizes on a more manageable 7-8%. The view opens up towards the top and if you keep your eyes open, you’ll see some local bovine residents.
