When it's summer in the Northern Hemisphere, it's winter in the Southern. Rio is the setting for perhaps the planet's most sensuous run July 17. The route -- which visually rivals any --sambas through city streets. It starts out in Reciero, and finishes up in Flamengo -- ocean to the left, and mountains to the right. Along the way runners weave through Praia da Reserva, Leblon, fabled Ipanema and Copacabana -- as on-lookers urge them on.
