LaCaze finished second in the 2012 Melbourne Track Classic in the 3000 metres steeple chase. LaCaze finished first at the 2012 Indianapolis American Milers Club in the 3000 metres steeple chase and first in the 1500 metres race.

LaCaze accepted an athletics scholarship to attend the University of Florida in Gainesville, Florida, to study Applied physiology and kinesiology. At the University of Florida she competed for the Florida Gators cross country and Florida Gators track and field teams in National Collegiate Athletics Association (NCAA) competition from 2009 to 2012. She competed in the university-hosted Mountain Dew Invitational held at the Mark Bostick Golf Course in Gainesville. She finished fifth at the 2011 NCAA Division I Track and Field Championships in the 3000 metres steeple chase, and second in the 2012 NCAA Division I Track and Field Championships in the same event, both held in Des Moines, Iowa.

LaCaze had a disappointing 2013 after breaking her ankle at the Birmingham Diamond League event in the buildup to the Moscow World Championships, for which she had qualified. This injury made LaCaze call time on life in Florida where she had carried on living and training since graduating college in 2012 after the Olympics. LaCaze returned home and based herself in Melbourne training with Melbourne Track Club giving her the opportunity to train with Australia’s best distance athletes and coach Nic Bideau. Since moving to Melbourne LaCaze has begun a relationship with fellow distance runner Ryan Gregson, whom she first met in 2007 under rather amusing circumstances.

LaCaze set an Olympic Qualifying time of 9:45, in June 2015 at the New York Diamond League well before deadline set by Athletics Australia. Australian Olympic Committee selected LaCaze to make her third team. LaCaze was paired with Australia female runner in the 3000 metre steeplechase event who set an Olympic Qualifying time: Madeline Heiner Hills and Victoria Mitchell.
