All club records are set in official races rather than internal club races such as the monthly mile handicap.
Athletes must be members of Crook AC on the day of competition and be representing Crook or a school, county, region or nation and not representing another second or first claim club.
If any athletes have historic times they feel should be on the lists, please email details and any supporting evidence, such as results sheets or newspaper clippings, to enquiries@crookac.co.uk
Junior and veteran club records are compiled from information recorded on UK Athletics’ Runbritain and Power of 10 websites which only date back to 2004.
