Ashleigh, who recently won the 2017 ITU World Triathlon Montréal, trains with the Australian Institute of Sport and the Queensland Academy of Sport. In 2004, a family friend persuaded her to take up triathlon. Initially, this was to improve her running times, but she soon found that she enjoyed the swimming and cycling too. She won silver at the Junior World Championships in Hamburg in 2007 and Vancouver in 2008 before winning in Budapest in 2010. In 2011, she ran in her first ITU World Triathlon Series (WTS) event, and was placed ninth.
In 2012 and 2013, she ran in ten WTS events, and was placed in the top ten in all of them. Being coached by Cliff English since 2014, she won silver in Yokohama in 2015 and 2016, and in Abu Dhabi in 2016. By May 2016, she was ranked third in the world and in the same year, the Australian Olympic Committee announced Gentle’s selection as one of six triathletes who would represent Australia at the 2016 Summer Olympics in Rio de Janeiro, her first Olympics, where she placed 26th. Most recently she won the 2017 ITU World Triathlon Montréal and took second place at the 2017 ITU World Triathlon Hamburg.
