Training under the tutelage of Josh Williamson in the High Performance Two squad (HP2) at the University of Stirling, Carter's impressive performances in 2022 at the February selection meet in Aberdeen earnt him a place among the thirty-strong team named for the World Para Swimming Championships.
Ollie Carter's first started swimming at his local club Cupar and District SC following aqua therapy sessions to help him learn to walk again after a final major lower leg operation at the age of ten. Having been born with his legs facing the wrong way, being in the water was an aid to building up the required muscle throughout the recovery process. Carter was introduced to the para-swimming pathway by Scottish Swimming at 13 and moved to Carnegie SC at 15 before heading to swim at the University of Stirling after high school.
