How about 18260 meters? Some people don’t do that in a season. 38 year old Forent Perrier, who has 11 world cup titles in ski mountainerring has just achieved this on the 25 March at Arêches. That’s over 750m/hour over a whole day. Incroyable. His going into retirement now, well earned I would say.
Tnanks to http://skitour.fr/ for the heads up.
