I was once visitin WW1 trenches near Ornavasso (the village of Elisa Longo Borghini) and there was this sign explaining like 9-10% gradient are the most efficient when you use donkeys as transportation, that is apparently the reason why so many road in the alps are like that.
And I may have read somewhere else that some of those donkeys were turned into racehorses.
