In this photo by Andy Brownbill, jockey Michelle Payne celebrates after riding Prince Of Penzance to victory in the Melbourne Cup, Australia's richest horse race. She is only the fifth woman to ride a horse in the Cup and the first to win. She's ridden the 6-year-old horse all of his racing career and says she's always considered him a potential Melbourne Cup winner. ''He just burst to the front and I've never yelled so loud at a horse in all my life. This is everybody's dream as a jockey in Australia.'' The Melbourne Cup, raced since 1861, is known as ''the race that stops a nation.'' Australians traditionally stop work at 3 p.m. on the first Tuesday in November to watch the two-mile race at Melbourne's Flemington racecourse. The horse was a 100-1 outsider in betting before the race, worth AU$6.2 million ($4.4 million) this year.
