The name – which sounds like the German word for “torture” – says it all: this race is not for the faint-hearted.

August 19 – 22, 2021

The biggest multiday, nonstop, ultracycling event in the world starts and ends in Zurich. Starting from Sihlcity shopping and leisure center, the solo riders and teams will cover more than 1,000 kilometers (620 miles) in just two days.

The strenuous adventure leads along the beautiful Lake Zurich into Central Switzerland and as far as the Swiss Alps. The route also crosses French-speaking Western Switzerland before heading back to Zurich. This means that on their tour through Switzerland, the dauntless athletes will also have to conquer a number of meters in altitude.

The race, which continues through the day and night, promises a host of emotions and a unique cycling experience.
