Meta Analyses

The analyses in this section relate to the database itself, providing information as to the quantity and quality of the information contained in the ADR database. Because of discontinuities in data collection, one should not interpret analyses presented in this section as reflecting the details of year-to-year changes in distance running world-wide but rather reflect general trends. Certainly the numbers of performances qualifying for inclusion in the ADR database has grown since the 1970's, however the factor is not as large as might be inferred from these analyses since coverage has tended to improve in recent years.

Current Statistics







Runners- qualified by time


Runners- other
Notes: The count of performances and races includes grand prix standings, splits, qualifying heats, and stage races. The runners qualified by time represent those that have achieved at least one of the ARRS time standards. Other runners include marathon winners, veterans under the qualifying standards for their age group, and runners who have won a single prize purse of US$1000 or more, that are not otherwise qualified by time.
