Starting with the 2014-2015 indoor season, the leading performances in each event (at senior level) by Athletics Louth athletes are shown. The best known performance in each event is shown, along with additional performances which match or exceed standards based on those used by the UK Power of 10 and Tops in Athletics ranking websites (as at April 2015), and by the World Athletics Scoring Tables.

In the hurdles, steeplechase and throws only performances with the senior hurdle heights/hurdle spacings/implement weights are included.

From the 2019-2020 indoor season, it is hoped to include some additional performances - e.g. with hurdles 3 inches below the senior height (but with senior spacings) and with the next heaviest throwing implement.

A new all-time list (with higher standards) was added for the first time in December 2018.
