[3] After the Pan Am Games, Overholt practiced her turns heavily to ensure no similar problems at the 2015 World Aquatics Championships in Russia.

She has signed into the University of British Columbia for a degree in science, but deferred her studies and participation in the UBC Thunderbirds until after the 2016 Summer Olympics.

[10] Despite thinking her Olympic participation was over, when Brittany MacLean could not attend the 4 × 200 m relay qualifying heats due to illness, Overholt was called in to replace her and helped the team reach the finals.

[14] She was then absent from the U Sports season and the Team Canada trials for the 2017 World Championship for not having fully overcome the hamstring injury.

[20] In June 2021, Overholt announced she was retiring as even after undergoing surgery early in the year, her body had not recovered well enough for her to remain competitive.
