Chris, OKey I won't. It's being:

Pbehn, I'll try to earn my popcorn but I'm not sure exactly what you are referring to when you say "as close as possible". First, there is not a Northern sailing route as a lot of land masses are in the way and the Arctic Ocean is blocked by constantly shifting sea ice.
Now going south is possible though weather conditions steadily worsen as you proceed further and further South since their are no landmasses to block wind or warm currents to moderate conditions. The names of the southern latitudes are very descriptive, i.e. Roaring Forties, Furious Fifties, Screaming Sixties.
Therefore, all of the Yacht races are generally along the old clipper ship route: From England/France/Spain down (south) the Atlantic Ocean to the Cape of Good Hope; then clockwise around the Cape, keeping Cape Hope to port; then East towards Australia. On this leg, the ships will be in the Roaring Forties or Furious Fifties (40-49 degree South Latitudes and 50-59 degree South Latitudes). The winds here blow from the west to the east with a good degree of force. In addition the ships will be in the Antarctic Circumpolar Current which also flows west to east.
The race then rounds the southern tip of Australia and continues East towards Cape Horn. Rounding the Horn west to east the race turns North up the coast of South America, across the Atlantic Ocean returning to their starting point. The race generally runs from November to February, and is timed to place the competitors in the Southern Ocean during the austral summer when wind/weather conditions have moderated to some extent.
Probably the toughest race was the Global Challenge run every four years starting in 1992. What made this unique was the direction of the race, from the East to the West, against the prevailing winds and currents. The route has varied but in 2004/5 started from Portsmouth (UK) and stopped at Buenos Aires (ARG), Wellington (NZ), Sydney (AUS), Cape Town (SA), Boston (USA) and La Rochelle (FRA) before returning again to Portsmouth.
