Any bigger margin of victory at the Belmont Stakes than in 1982?

Question

Conquistador Cielo in the slop crushed the field by at least 20 lengths.

Answer 1

Not even close to the record.

Secretariat by 31 in 1973.

Answer 2

A horse named Secretariat (ever hear of him?) won the Belmont by a widening 31 lengths in 1973 to complete his Triple Crown bid.

Almost everyone who watched that race agrees that Secretariat could have won by an even greater margin if jockey Ron Turcotte had asked him to.
