The Rational Rest Day
Tomorrow there is an event in Cossonay that could easily involve cycling fourty kilometres to get there, and cycling whilst there, and then cycling back. The low estimate would be an eighty kilometre day and the high estimate would be at least a century.
I was looking at the train, from Nyon to Cossonay, but the connection in Renens is four minutes. Plenty of time, in theory to swap from one track to the other, but with sluggish people that seems less likely.
