(CNN) -- On the last day of 2010, 14 teams set sail from Barcelona for one of the toughest sporting events in the world.
A two-crew sailing race around the world, the Barcelona World Race pushes athletes to their edge, testing their stamina, skills and mental resilience.
For roughly three months, the competitors are stuck in cramped quarters with just one other person as they race non-stop around the world.
The course runs from Barcelona to Barcelona via three capes -- Good Hope, Leeuwin and Horn.
The Virbac-Paprec 3, the first boat to enter New Zealand's Cook strait, currently leads the race.
