Hayley first got into the sport when she completed the swim section of a team triathlon with two of her colleagues in 2014, who eventually convinced her to do a super sprint triathlon in 2016 and join Greenwich Tritons Triathlon Club where a coach suggested that Hayley try for the Great Britain Age Group team in 2018. Since January 2018, she has been training six days a week and competing in the selection races to qualify for the international races.
