Athletic career

Tanner was admitted to the national team when she first competed for the junior category at the 2000 ITU World Championships in Perth, and since then, she had proven her tenacity, endurance, and positivity to reach into a higher level within the international scene. In 2006, Tanner qualified for the 2006 Commonwealth Games in Melbourne, and was selected to the national team; however, her training and willpower was insufficiently enough to win a medal, as she finished fourth in the women's triathlon, just behind her compatriot Andrea Hewitt.^[3] Despite her sudden and disappointing result, Tanner recaptured her success and triumph at the ITU World Triathlon Cup in the same year, as she clinched her major international title in Ishigaki. Following her first triumph, Tanner continued to stand on the podiums at World Cup events, by obtaining the silver in Hamburg, and three bronze medals at different locations across Europe and Asia. In addition to her five World Cup medals, Tanner had achieved nine more finishes in the top ten position.^[1]

Tanner competed at the 2008 Summer Olympics in Beijing for the first time, where she placed tenth in the women's triathlon, just behind her compatriot Hewitt by just two places, with the time of 2:01:06. Her participation and fair performance at the Olympics reinforced her ambition of striving to be the best triathlete for New Zealand, and for an Olympic gold medal at the subsequent games. In 2009, Tanner achieved her target by winning the gold medal at the ITU Triathlon Oceania Cup in Wellington. She also performed consistently by taking part in seven competitions of the Dextro Energy World Championship Series, where she only obtained a top ten finish, without winning a single medal. Tanner, however, was beaten again by Hewitt at the 2010 OTU Triathlon Oceania Championships in Wellington, where she finished only in second place.

With her consistent performance being ended up in poor results at a span of three years, Tanner missed out on the national team for the 2012 Summer Olympics in London.^[4] On 20 October 2012, Tanner announced her retirement in triathlon, following the women's event at the Barfoot & Thompson World Triathlon Grand Final in Auckland.^[5]
