Like every year, there will be a free-for-everyone bike ride around Lake Zurich on Ascension Day. Start is between 6 and 9, you have to be done by 12.30, the fee is CHF 30. Unfortunately for the bike riders, the roads are not closed. For those starting in Zurich, last year, the checkpoint was near Enge.
I am not sure yet whether I am going, it will depend on the weather.
