Buchenegg Bergzeitfahren, or Buchenegg BZF for short, Zürich's local hill-climbing time trial. Taking place every year in late Summer, this climb ascends two-hundred and thirty meters over three kilometers for an average gradient of 8%, but with several pitches over 10%, ending with a false flat leading to the pass's restaurant. The ride starts with a gentle 1.5 kilometer warm up before leading into the hill-climb segment.
