Two time Olympian, Sarah Lavin finished 32nd in her first Games at Tokyo 2020. At the Paris 2024 Games, Lavin delivered an assured performance in her initial heat, finishing third with a time of 12.87 seconds and securing a place in the semifinals. In the semifinal round, she improved her time to 12.82 seconds but narrowly missed qualifying for the final.​

A European Youth Olympic bronze medallist in 2011 and a European Junior silver medallist in 2013, Sarah finally won her first senior medal – bronze at the European Games – in 2023. She also broke Derval O’Rourke’s long-standing senior record at World Championships and finished 2023 by breaking the Irish 100m flat record (11:27).

In an event where medals are decided by 1000ths of a second she has come agonisingly close to other podiums; fourth at the 2019 World Student Games, fifth at the 2022 Europeans, and twice a World semi-finalist.
