John Nelson (swimmer)
[4][1] As a Sophomore at Yale in April 1968, Nelson looked forward to the Mexico City Olympics, but realized how much tougher the competition would be to make the U.S. team.Chavoor was one of the early coaches to challenge elite swimmers with "overdistance training", which focused on workouts that gave more total yardage and semi-frequent mid-range and longer distance intervals to build greater endurance and speed.[1] Nelson qualified at the trials and subsequently competed at the 1968 Olympic Games in Mexico City, where he received a gold medal in the men's 4×200-meter freestyle relay beside his teammates Stephen Rerych, Mark Spitz and Schollander.[4] In individual competition, Nelson received the bronze medal for his third-place finish in the men's 200-meter freestyle with a time of 1:58.1.[6][4] Nelson improved the world record on the 400-meter freestyle (long course) on August 18, 1966 (4:11.8), only to be beaten by Don Schollander, both a Yale and U.S. Olympic teammate, on the same day (4:11.6).
