Non is a member of the UK Sport Lottery Funded World-Class Performance Squad and is based at the Leeds Performance Centre. Non was the ITU World Champion in 2013 and represented Team GB at the Rio 2016 Olympic Games, where she finished 4th.
Competing in her first Olympics in Rio in August 2016, Non finished in an agonising 4th place, losing out on the bronze medal to teammate and friend Vicky Holland in a sprint for the finish line.
Non made a successul transition from track running to triathlon. 2012 was a breakthrough year, with senior gold in the ITU Triathlon Mixed Relay and U23 gold at the ITU World Championships. 2013 started with real impact with a win in the ITU World Triathlon Series in Madrid, before going on to win the Series title in London. Along the way she achieved podium finishes in San Diego, Hamburg and Stockholm.
Due to injury, Non's entire 2014 season was missed, but she came back strongly in 2015 to finish second at the Rio Oympic Test Event and the ITU World Triathlon Grand Final in Chicago - meeting the British Triathlon Olympic selection criteria in the process. 2017 was once again affected by injury, but she did achieve and ITU World Cup win in Chengdu, China.
Non won the ITU world title in London in 2013 having won the U23 title the previous year.
Non was born in Bridgend, lived in Swansea and went to University in Birmingham before relocating to Leeds.
She changed her focus from running (she was Welsh Schools 1,500m champion in ’02, ’03 and ’04) to triathlon after a series of injuries kept her off the track. Non had been picked out as a bright young running talent in 2004 when she was invited to join Kelly Holmes on the first ever 'On Camp with Kelly' at a camp in South Africa. In 2006 she finished 3rd in the 3000m (senior) at the AAA Indoor championships. She took up triathlon seriously with the University of Birmingham Triathlon team.
