The race that stops a nation — the Melbourne Cup is run on the first Tuesday of November at Flemington Racecourse and is Australia’s most celebrated horse race. The four-day Melbourne Cup Carnival is as much about fashion and festivity as racing, with Oaks Day (Ladies’ Day) featuring extraordinary millinery. The Cup itself is a public holiday in Melbourne, and workplaces across the country pause for the 3-minute race. Stakes: AUD 8 million. Dress code: spectacular.
