One of the most decorated triathletes ever to participate in the sport, Hewitt has won multiple medals at World Championship level, including gold at the 2005 ITU World U23 Championships, silver in the 2011 and 2015 ITU World Championships, bronze in the 2009 and 2014 ITU World Championships and to highlight her versatility Hewitt has won bronze medals at both the ITU Long (2014) and Sprint distance (2011) World Championships.
Known for her consistency, the other athletes know that if Hewitt is racing, she will be a contender on the back of strong swimming borne of her surf lifesaving background, aggressive bike riding and one of the best runs in the sport.
Hewitt was coached by her fiancée Laurent Vidal until his tragic passing in late 2015 and has since teamed up with Chris Pilone with support from her first coach John Hellemans. Her results in 2016 have been typically consistent and world class, with a silver medal at the Quality Hotel new Plymouth World Cup, bronze medal at the ITU Gold Coast WTS event and a fourth place at the ITU Yokohama WTS event.
Hewitt has significant experience at major games, with a bronze medal at the 2006 Commonwealth Games, 8th place at the 2008 Olympics and 6th place at the 2012 London Olympic Games.
Hewitt has a degree in Economics from Canterbury University and when not racing or training loves to indulge in travel, jewelry making and a bit of body surfing – testament to her beginnings in surf lifesaving.
