Her final attempt at the title, in 2015, was cut short by a torn Achilles. Foucher tore her Achilles during an event on the second day of the 2015 Central Regional during Event 3. Appearing devastated in video interviews immediately after the injury, it appeared to be the end of her career. However, later that day, Foucher returned to the competition floor wearing a large black medical boot. As the other athletes ran across the competition floor to begin the 250-ft. handstand walk, Foucher walked with the boot jutted out to the side. Even with the injury, Foucher managed to finish in 2:17 for 11th on the event. She continued on to lift, albeit a small load, in the max snatch (85-lb.), and returned the next day to compete in the final events. She earned a remarkable 8th-place finish on the triplet of rowing, chest-to-bar pull-ups, and strict deficit handstand push-ups, and closed out by completing the 15 muscle-ups of the final event while skipping the 5 cleans that followed.
2015 was her last CrossFit Games season; in the future she intends to focus her full attention on her work as a doctor and CrossFit seminar trainer. She says that her ultimate dream is to have a CrossFit affiliate tied to her medical practice, such that there is an open community between both.
