Following a leg injury in 2013, LaCaze returned to Australia and joined the Melbourne Track Club, training under coach Nic Bideau. This pivotal period led to a strong performance at the 2014 Commonwealth Games where she finished fifth in the 3000-meter steeplechase, setting a new personal best time. LaCaze’s second Olympic appearance came at the Rio 2016 Olympic Games, a highly successful campaign where she achieved multiple personal bests, securing ninth place in the 3000-meter steeplechase and twelfth in the 5000-meters finals. Her global recognition continued with a twelfth-place finish at the 2017 World Championships in the 3000-meter steeplechase, followed by another fifth-place finish at the 2018 Commonwealth Games in the same event.
She made her marathon debut in July 2023 at the Gold Coast, recording the second-fastest debut time by an Australian woman, and in December 2023, achieved a time of 2:23:08 at the Valencia Marathon, ranking her third all-time among Australian women. In 2024, LaCaze represented Australia in the marathon at the Paris 2024 Olympic Games, finishing 24th. Further demonstrating her remarkable career progression and resilience, she also won the Melbourne Marathon in 2024.
