Introduction

This database has been created entirely thru volunteer efforts. Many hundreds of people have contributed race results and other useful information over a period of many years. Some of these people have spent a great deal of time vetting the information in this database, correcting errors, adding missing information, and providing ancillary information. If you find what you believe to be an error, please send documentation for the correct information to info@arrs.run.

The ARRS also maintains a static website (www.arrs.run) that has a wide variety of statistics that are supplementary to this interactive website.

Criteria for Inclusion in the ARRS Database

Only performances at distances of 3000m or longer are included. Steeplechase performances are not included. Performances include road, off-road, and outdoor and indoor track races. Road relay and stage races are also included.

There are two tiers of runners included in this database.

The “elite” tier consists of runners who have achieved at least one of the ARRS qualifying standards (www.arrs.run/ADR_Crit2.htm). All of the performances by runners in the elite tier (distances 3000m and longer) are eligible for the database, including dnf’s and dq’s.

The second tier (sub-elite) consists of runners that have met one or more of the following standards but do not qualify for the elite tier:

  1. won a prize money award of US$1000 or more.
  2. achieved a performance that makes one or more of the all-time age group lists.
  3. won a marathon.
  4. other runners of particular interest.

For the sub-elite runners, additional performances are included as follows:

  1. marathon and ultra-marathon performances, regardless of placing.
  2. performances where prize money was awarded.
  3. performances as a veteran at standard (record) distances.
  4. national championship title or national record performances.
  5. other performances of particular interest.
What this means to you as a user is that the results provided for any given race reflect these criteria and are not intended to be complete beyond the ARRS qualifying standards.

Classification of Races

Races are classified as road, crosscountry, outdoor track, or indoor track.

Outdoor tracks cannot be larger than 440 yards. Outdoor track races are considered to be “road” races if the circuit is greater than 440 yards.

Indoor track races are considered to be over-sized If the circuit is greater than 220 yards (indicated with an “a”) and considered to be “road” races if the circuit is greater than 440 yards.

Courses that are a mixture of road, off-road, and/or track are usually classified by the predominant type.

All off-road (and off-track) races are classified as crosscountry races, including trail races. Hill climbs mostly on roads are considered as road races.

Road Course Accuracy

Course certification status is indicated for a small fraction of the races in the database. If this has been determined, it is indicated and certification codes are included.

The results for many of the standard distance road races in this database have been analyzed statistically in order to assess the accuracy of the race course. This analysis returns a statistic termed the “race time bias” or RTB for short. Values of the RTB that are more negative (faster) than -5.0 sec/km indicate there is a problem with the course and the results are probably not valid, i.e., they should be excluded from rankings and records. The problem could be a short course, or the course could be downhill or the race may have been wind-aided.

Ranking and Record Criteria

There are three classifications for performances (for road races):

  1. Record quality - performances made on record-quality courses (net drop not greater than 1 m/km and a start to finish straight-line separation of not more than 30%).
  2. Statistically invalid – performances achieved on courses that have a net drop of more than 5 m/km, courses that have been shown to have been short, and races that the statistical analysis indicates are not valid. These performances are indicated with an “x” suffixed to the time and are not included in rankings or records lists.
  3. Statistically Valid – all other performances. These performances are included in rankings (but not records) and indicated with an “a” suffixed to the time.

Extensive efforts have been made to provide gun times for all results in the database. Where only net times were provided or it is likely that the times are net times, these performances are considered statistically invalid and indicated with an “x”. This helps to ensure that the performances in this database were achieved in bona fide competition.

Rankings

The rankings are not intended to be complete beyond the ARRS qualifying standards. Performance lists are not intended to be complete for sub-elite tier runners, as they are for elite tier runners. Veteran’s performances are included in the veteran’s rankings, ONLY if a date of birth has been provided.

Prize money

Prize money is indicated in US dollars. Prize monies awarded in other currencies have been converted at the prevailing exchange rate at the time of the race.
