Club records are recognised as times set at the age the swimmer was on the day of the swim, regardless of the age group category used at the gala.

Results Database
Here are links for searching the ASA national database records for personal best times and national, regional, county and club rankings from Licensed meets.  The individual best times view has links to historic data held on the Swim England database for each event.  This gives you a graphical view of your performance improvement over time - great for reminding yourself how far you've come on your swimming journey!
