Leanda has been competing in triathlons since 1994. She began her triathlon career at the Olympic distance and gradually made her way to dominating long course triathlon. In 2001 Leanda became European Under- 23 champion. A year later she would break through at the international level as she won the silver medal at the 2002 Commonwealth Games in Manchester. She won another silver medal at the European Championships, then had greater success when she took the gold and the World title in Cancun, Mexico in November 2002. In 2002 she was nominated for the Welsh Sports Personality of the Year Award, a feat that she repeated in 2012. In 2012 Leanda was also named as one of the “World’s Fittest Women” by CNN. This is quite a recognition as 2012 was also an Olympic year.

In 2007 Leanda went on to win her second world title at the ITU Long Distance World Championships in France. From this point forward she won numerous long course races around the world, including: Escape from Alcatraz (4X), Florida 70.3 (3X), Miami 70.3 (3X), Wildflower Long Distance Triathlon, and Ironman Arizona.

In 2012, Leanda won both the IM 70.3 World Championships and IM World Championships, the first female triathlete in history to accomplish both feats in a single year.

Leanda was born in England, moved to Australia when she was only 4 and eventually moved back to the UK where she chose to represent Wales in triathlon. In 2008 Cave moved to United States, she currently lives and trains in Miami Beach when she’s not racing.
