I believe Carl Lewis won four straight long jump golds. But were it not for Lewis, Oerter would have I think the record in track and field for consecutive Olympic golds. Amazing achievement. RIP.
I believe that Oerter also set a new olympic record with each of his 4 golds.
As tickmeister pointed out, Oerter set Olympic records each time. Lewis did not (no one has bested Bob Beamon's 1968 Mexico City effort).
But were it not for Lewis, Oerter would have I think the record in track and field for consecutive Olympic golds.
