In the 1960s there were at least 3 WORLD RECORDS set by college teams in the one or four lap relays.
Oregon 440 Relay
USC 440 Relay
Arizona State Mile Relay
Are there any links out there showing a World Record Progression Listing for the Mile Relay (not the 4 x 400 meters)?
Is there a similar World Record Progression Listing for the 440 Relay (not the 4 x 100meters)?
Has a College Relay Team set the 4 x 1 or 4 x 440 / 400 WORLD RECORD since those three College World Records in the 1960s?
Specific links / sources would be helpful.
