When Alison King moved to New Zealand she was "pretty lazy".
Thirteen years later she has completed four Ironman races, 11 marathons, about 15 half marathons and five half Ironman races.
She has turned her life around and just 14 days after competing at the Rotorua Marathon she will be on the start line at the inaugural Air New Zealand Hawke's Bay International Marathon on May 14.
Ms King said she was "pretty lazy", eating a lot of fast food. Then she joined Weight Watchers, which led her to aqua aerobics and swimming.
The Rotorua mum heard about the Special K triathlons and saw some photos of women larger than her, and thought if they could do a triathlon then she could too.
