Swimming: Six major swimsover - one to go

Bula Chowdhury has added Cook Strait to a swimming trek that has spanned four years and six of the world's most difficult swims.

Chowdhury became the second Indian woman to swim Cook Strait, and just the 56th person overall, in nine hours and four minutes from Wellington to Perano Head in the South Island.

Chowdhury, who holds Indian records for the 100m and 200m butterfly, now has just one swim left, in South Africa, to complete her dream of swimming seven of the world's toughest seas.

Since 1999 the 31-year-old mother of one has swum the English Channel, the Tyrrhenian Sea in Italy, the Strait of Gibraltar, the Catalina Channel in the United States, the Toroneus Gulf in Greece, and now Cook Strait.
