Record keeping varies widely from country to country. Most countries do not recognize road records. The following is an attempt to list national records using a consistent set of standards. Records reflect performances in the ADR database. Since the ADR database only tracks runners who have met certain time standards, there will be national records that are excluded from these lists since they do not meet the criteria for inclusion in the ADR database.
Citizenship is determined as of the date of the race with exceptions for countries
that have since merged or split. In such cases, citizenship is assigned according to current countries. East and
West Germany are both indicated by GER; runners representing the former Soviet Union are assigned to currently
existing countries where known.. ENG, NIR, SCO, and WAL are listed as well as GBR.
World road records for women as recognized by the ARRS must be set in women-only competition. The world marks listed in this section were usually made in mixed competition, consistent with the national road records which also include mixed competition.
Record quality performances are those made on standard (loop or out-and-back) courses that are believed to be accurate. Courses are not considered standard if the start and finish lie more than 30% of the race distance apart and/or whose drop exceeds 1 meter per kilometer. Times with "^" appended are enroute times.
Indoor Track Records
Marks achieved on indoor tracks of 200 meters or less are included. Times to hundredths of seconds are auto-times; times to tenths of seconds are hand times.
Outdoor Track Records
Times to hundredths of seconds are auto-times; times to tenths of seconds are hand times.
