At vet school I remember one of my farm lecturers comparing a dairy cow to a Tour de France cyclist, which having watched the cycling last month, does seem a little extreme. The Tour de France sees cyclists covering over 2100 miles over 3 weeks, including grueling mountain stages in The Pyrenees and The Alps. Seeing the competitors cycle up and down mountains for 4-5 hours a day and pretty much pass out at the top does not seem comparable to the dairy cow just standing and merrily chewing the cud. So, I thought I would crunch the numbers and see why my lecturer made this comparison.
