"Dear ultra runners,

"Rankings are generated of this database if the event was ranking eligible. All lists are linked to each other by hyperlinks. Clicking on the name of an athlete takes you to an overview of all results for this runner. Clicking on the name of an event takes you to the complete results list of this race."
From Sahishnu, an associate Race Director of the Sri Chinmoy Marathon Team:
"I am responsible for statistics from our New York multi-day races, held from 1985 to 2017- here in New York. The various European and Asia/Oceana Sri Chinmoy Marathon Teams are responsible for results in their own races in their countries. The lists that I keep are from 1000 km up to 3100 miles and 5000km. The shorter distance races/ultras the other Sri Chinmoy Marathon Teams send, accordingly, directly to D.U.V. If and when someone sets a new record on the lists, I send the info with proper certification to the governing bodies - USATF and IAU. I also search and add results when available from other races if applicable to the longer distance lists mentioned above."
