A selection of Irish records over standard ultra distances is outlined below. Please note there is a minimum distance or time standard required before a performance is accepted as a national record / best. For example, women's track 24 hours would require a standard of 200km in line with Grade B international selection criteria for outdoor championships. The event must also be an IAU-labelled race or otherwise approved by UltraRunning Ireland for record-setting purposes. Athletes attempting 'inter-city' or point to point records should notify UltraRunning Ireland in advance if they want assistance in having a record ratified - and to verify existing records.
